The bpf syscall and selftests conflicts were trivial
overlapping changes.
The r8169 change involved moving the added mdelay from 'net' into a
different function.
A TLS close bug fix overlapped with the splitting of the TLS state
into separate TX and RX parts. I just expanded the tests in the bug
fix from "ctx->conf == X" into "ctx->tx_conf == X && ctx->rx_conf
== X".

When computing the bitrate using values read from an SFP module EEPROM,
we use the nominal BR plus BR,min and BR,max to determine the
boundaries. But in some cases BR,min and BR,max aren't provided, which
led the SFP code to end up having the nominal value for both the minimum
and maximum bitrate values. When using a passive cable, the nominal
value should be used as the maximum one, and there is no minimum one
so we should use 0.

In an SFP EEPROM values can be read to get information about a given SFP
module. One of those is the bitrate, which can be determined using a
nominal bitrate in addition with min and max values (in %). The SFP code
currently compute both BR,min and BR,max values thanks to this nominal
and min,max values.
This patch fixes the BR,min computation as the min value should be
subtracted to the nominal one, not added.

Provide a pointer to the SFP bus in struct net_device, so that the
ethtool module EEPROM methods can access the SFP directly, rather
than needing every user to provide a hook for it.

Negotiate the interface format with the MAC rather than requiring it to
be a fixed type specified solely by the SFP module. This allows modules
that can work with several different interface signalling formats to
select a format compatible with the MAC - for example, a Fiber module
supporing Gigabit ethernet and faster connected to a Gigabit only MAC
needs to select the 1000BASE-X mode.

Some BiDi modules (eg, FiberStore SFP-GE-BX) are not compliant with
1000BASE-BX as they use different wavelengths from the 1000BASE-BX
standard (eg, 1310nm/1550nm rather than 1310nm/1490nm). These modules
support 1000BASE-X ethernet, so detect them by a failure to find any
other support, the 8B10B encoding and a bit rate that falls within the
1Gbps window.

Improve the support for direct-attach copper so that we avoid kernel

Direct Attach cables can use a number of protocols depending on their
