Benjamin LaHaise ff67df55f6 vxge: fix pktgen hangs (don't abuse skb->cb[]) 
This patch fixes a case in the transmit completion code which was resulting
in pktgen hanging at the end of a run.  The cause is due to the fact that
the ->cb[] area of an skb cannot be used in a network driver's transmit
path, as that area belongs to the network protocol.  Pktgen hangs, as it
sends out the same packet multiple times, and vxge's use of this area of
the skb for a temporary list can only add the packet to the temporary list
once (while it may be on the queue many times).  The fix is to remove this
abuse of skb->cb[].  Instead, skb pointers are placed into a temporary
stack array, and then free outside of the tx lock.  This retains the smp
optimization of doing dev_kfree_skb() outside of the tx lock.

* containing retransmitted octets.
* @tx_rst_tcp: Count of transmitted TCP segments containing the RST flag.
* @tx_udp: Count of transmitted UDP datagrams.
* @tx_parse_error: Increments when the TPA is unable to parse a packet. This
* generally occurs when a packet is corrupt somehow, including
* packets that have IP version mismatches, invalid Layer 2 control
* fields, etc. L3/L4 checksums are not offloaded, but the packet
* is still be transmitted.
* @tx_unknown_protocol: Increments when the TPA encounters an unknown
* protocol, such as a new IPv6 extension header, or an unsupported
* Routing Type. The packet still has a checksum calculated but it
* may be incorrect.
* @tx_pause_ctrl_frms: Count of MAC PAUSE control frames that are transmitted.
* Since, the only control frames supported by this device are
* PAUSE frames, this register is a count of all transmitted MAC
* control frames.

* on this Aggregation port.
* @tx_lacpdu_frms: Count of LACPDUs transmitted on this Aggregation port.

* 1) An internal processing error
* (such as an uncorrectable ECC error). 2) A frame parsing error
* during IP checksum calculation.
* @tx_marker_resp_pdu_frms: Count of Marker Response PDUs transmitted on this
* Aggregation port.
* @tx_xgmii_char2_match: Maintains a count of the number of transmitted XGMII
* characters that match a pattern that is programmable through
* register XMAC_STATS_TX_XGMII_CHAR_PORTn. By default, the pattern
* is set to /T/ (i.e. the terminate character), thus the statistic
* tracks the number of transmitted Terminate characters.
* @tx_xgmii_char1_match: Maintains a count of the number of transmitted XGMII
* characters that match a pattern that is programmable through
* register XMAC_STATS_TX_XGMII_CHAR_PORTn. By default, the pattern
* is set to /S/ (i.e. the start character),

* @tx_xgmii_column2_match: Maintains a count of the number of transmitted XGMII
* columns that match a pattern that is programmable through register
* XMAC_STATS_TX_XGMII_COLUMN2_PORTn. By default, the pattern is set
* to 4 x /E/ (i.e. a column containing all error characters), thus

* any time. If XMAC_STATS_TX_XGMII_BEHAV_COLUMN2_PORTn.NEAR_COL1 is
* set to 1, then this stat increments when COLUMN2 is found within
* 'n' clocks after COLUMN1. Here, 'n' is defined by
* XMAC_STATS_TX_XGMII_BEHAV_COLUMN2_PORTn.NUM_COL (if 'n' is set
* to 0, then it means to search anywhere for COLUMN2).
* @tx_xgmii_column1_match: Maintains a count of the number of transmitted XGMII
* columns that match a pattern that is programmable through register
* XMAC_STATS_TX_XGMII_COLUMN1_PORTn. By default, the pattern is set
* to 4 x /I/ (i.e. a column containing all idle characters),
* thus the statistic tracks the number of transmitted Idle columns.
* @tx_any_err_frms: Count of transmitted frames containing any error that
* prevents them from being passed to the network. Increments if
* there is an ECC while reading the frame out of the transmit
* buffer. Also increments if the transmit protocol assist (TPA)
* block determines that the frame should not be sent.
* @tx_drop_frms: Count of frames that could not be sent for no other reason
* than internal MAC processing. Increments once whenever the
* transmit buffer is flushed (due to an ECC error on a memory
* descriptor).
* @rx_ttl_frms: Count of total received MAC frames, including frames received
* with frame-too-long, FCS, or length errors. This stat can be
* configured (see XMAC_STATS_GLOBAL_CFG.TTL_FRMS_HANDLING) to count
* everything, even "frames" as small one byte of preamble.
* @rx_vld_frms: Count of successfully received MAC frames. Does not include
* frames received with frame-too-long, FCS, or length errors.
* @rx_offload_frms: Count of offloaded received frames that are passed to
* the host.
* @rx_ttl_octets: Count of total octets of received frames, not including
* framing characters (i.e. less framing bits). To determine the
* total octets of received frames, including framing characters,
* multiply PORTn_RX_TTL_FRMS by 8 and add it to this stat (unless
* otherwise configured, this stat only counts frames that have 8
* bytes of preamble for each frame). This stat can be configured

* characters, of offloaded received frames that are passed
* to the host.
* @rx_vld_mcast_frms: Count of successfully received MAC frames containing a
* nonbroadcast group address. Does not include frames received
* with frame-too-long, FCS, or length errors.
* @rx_vld_bcast_frms: Count of successfully received MAC frames containing
* the broadcast group address. Does not include frames received

* @rx_accepted_ucast_frms: Count of successfully received frames containing

* the system.
* @rx_accepted_nucast_frms: Count of successfully received frames containing
* a non-unicast (broadcast or multicast) address. Only includes
* frames that are passed to the system. Could include, for instance,

* register is set to pass FCS-errored frames to the host.
* @rx_tagged_frms: Count of received frames containing a VLAN tag.
* @rx_long_frms: Count of received frames that are longer than RX_MAX_PYLD_LEN

* is nearly full -- this can happen if the external receive buffer
* is full and the receive path is backing up.
* @rx_red_discard: Count of received frames that are discarded because of RED
* (Random Early Discard).
* @rx_xgmii_ctrl_err_cnt: Maintains a count of unexpected or misplaced control
* characters occuring between times of normal data transmission

* 2) Start control character is not in lane 0
* Only increments the count by one for each XGMII column.
* @rx_xgmii_data_err_cnt: Maintains a count of unexpected control characters
* during normal data transmission. If the Reconciliation Sublayer
* (RS) receives a control character, other than a terminate control

* that match a pattern that is programmable through register
* XMAC_STATS_RX_XGMII_CHAR_PORTn. By default, the pattern is set
* to /E/ (i.e. the error character), thus the statistic tracks the
* number of Error characters received at any time.
* @rx_xgmii_err_sym: Count of the number of symbol errors in the received
* XGMII data (i.e. PHY indicates "Receive Error" on the XGMII).
* Only includes symbol errors that are observed between the XGMII
* Start Frame Delimiter and End Frame Delimiter, inclusive. And
* only increments the count by one for each frame.
* @rx_xgmii_column1_match: Maintains a count of the number of XGMII columns
* that match a pattern that is programmable through register
* XMAC_STATS_RX_XGMII_COLUMN1_PORTn. By default, the pattern is set
* to 4 x /E/ (i.e. a column containing all error characters), thus
* the statistic tracks the number of Error columns received at any
* time.
* @rx_xgmii_char2_match: Maintains a count of the number of XGMII characters
* that match a pattern that is programmable through register
* XMAC_STATS_RX_XGMII_CHAR_PORTn. By default, the pattern is set
* to /E/ (i.e. the error character), thus the statistic tracks the
* number of Error characters received at any time.
* @rx_local_fault: Maintains a count of the number of times that link
* transitioned from "up" to "down" due to a local fault.
* @rx_xgmii_column2_match: Maintains a count of the number of XGMII columns
* that match a pattern that is programmable through register
* XMAC_STATS_RX_XGMII_COLUMN2_PORTn. By default, the pattern is set
* to 4 x /E/ (i.e. a column containing all error characters), thus
* the statistic tracks the number of Error columns received at any
* time. If XMAC_STATS_RX_XGMII_BEHAV_COLUMN2_PORTn.NEAR_COL1 is set
* to 1, then this stat increments when COLUMN2 is found within 'n'
* clocks after COLUMN1. Here, 'n' is defined by
* XMAC_STATS_RX_XGMII_BEHAV_COLUMN2_PORTn.NUM_COL (if 'n' is set to
* 0, then it means to search anywhere for COLUMN2).
* @rx_jettison: Count of received frames that are jettisoned because internal
* buffers are full.
* @rx_remote_fault: Maintains a count of the number of times that link
* transitioned from "up" to "down" due to a remote fault.
