Contrarily to what i wrote in my previous commit, the 82599
does include the CRC in the length. The operating mode is
reset in ixgbe_init_locked() and so we need to hook into
the places where the two registers (HLREG0 and RDRXCTL) are
modified.
This uses the new firmware(9) method for squirreling away the EEPROM
contents from SPI flash so ath(4) can get to them later.
It won't work out of the box just yet - you have to add this to
if_ath_pci.c:
#define ATH_EEPROM_FIRMWARE
.. until I've added it as a configuration option and updated things.
interface.
* Introduce a device hint, 'eeprom_firmware', which is the name of firmware
to lookup.
* If the lookup succeeds, take a copy of it and use it as the eeprom data.
This isn't enabled by default - you have to define ATH_EEPROM_FIRMWARE.
I'll add it to the configuration variables in a later commit.

future use by the ath(4) driver.
These embedded devices put the calibration/PCI bootstrap data on the
on board SPI flash rather than on an EEPROM connected to the NIC.
For some boards, there's two NICs and two sets of EEPROM data in the
main SPI flash.
The particulars:
* Introduce ath_fixup_size, which is the size of the EEPROM area in
bytes.
* Create a firmware image with a name based on the PCI device identifier
(bus/slot/device/function).
* Hide some verbose debugging behind 'bootverbose'.
ath(4) can then use this to load in the EEPROM data.
This requires AR71XX_ATH_EEPROM to be defined.
* the openwrt code doesn't treat 0/0/0 any differently
from other bus/slot/func combinations.
* A "local write" function writes to the LCONF area, and
so I've added it.
* The PCI workaround at attach time uses this LCONF code,
which it already did ..
* .. but it is a 4 byte write, not a 2 byte write.
Even though it's PCIR_COMMAND which is a two byte PCI register.

Flags are now stored to ip->i_flags in one place after all checks.
Also, remove SF_NOUNLINK from the checks because ext2fs doesn't support

Very strange. Need to check what happens on legacy descriptors,
but for the time being this restores functionality.
Before, we took the first argument to pam_exec(8). With the addition of
options in front of the command, this could be wrong.
Now, options are parsed before calling _pam_exec() and messages contain
the proper command name.
While here, fix a warning.

we simply allocate new one in a newly added cylinder group.
This patch removes a conditional in updcsloc(), reindents some code
there, and removes unused routines. I decided to do it this way instead
of disabling reallocation when the filesystem is live and leaving it
as it is otherwise, because this allows for removal of lots of complicated
and hard to test code. Also, conditionally disabling it would result
in a different layout in filesystems resized online and offline, which
would look somewhat weird.

Attempting to use the returned page could then cause either memory
