68e7f45e11 sfc: Use generic MDIO functions and definitions
Make use of the newly-added generic MDIO clause 45 support and remove
redundant definitions.

Add an 'efx_' prefix to the remaining driver-specific MDIO functions
and remove arguments which are redundant with efx->mdio.prtad.

190dbcfd68 sfc: SFT9001/SFN4111T: Check PHY boot status during board initialisation
During SFN4111T initialisation, check whether the PHY boot status
indicates a bad firmware checksum.  If so, prepare to reflash rather
than continuing with normal initialisation.

Remove redundant PHY boot status check from tenxpress_phy_init().

1974cc205e sfc: Replace stats_enabled flag with a disable count
Currently we use a spin-lock to serialise statistics fetches and also
to inhibit them for short periods of time, plus a flag to
enable/disable statistics fetches for longer periods of time, during
online reset.  This was apparently insufficient to deal with the several
reasons for stats being disabled.

af4ad9bca0 sfc: SFX7101/SFT9001: Fix AN advertisements
All 10Xpress PHYs require autonegotiation all the time; enforce this
in the set_settings() method and do not treat it as a workaround.

Remove claimed support for 100M HD mode since it is not supported by
current firmware.

Do not set speed override bits when AN is enabled, and do not use
register 1.49192 for AN configuration as it can override what we set
elsewhere.

Always set the AN selector bits to 1 (802.3).

Fix confusion between Next Page and Extended Next Page.

2d18835d65 sfc: SFX7101: Remove workaround for bad link training
Early versions of the SFX7101 firmware could complete link training in
a state where it would not adequately cancel noise (Solarflare bug
10750).  We previously worked around this by resetting the PHY after
seeing many Ethernet CRC errors.  This workaround is unsafe since it
takes no account of the interval between errors; it also appears to
be unnecessary with production firmware.  Therefore remove it.

da3bc07171 sfc: Replace LRO with GRO
This patch makes sfc invoke the GRO hooks instead of LRO.  As
GRO has a compatible external interface to LRO this is a very
straightforward replacement.

Everything should appear identical to the user except that the
offload is now controlled by the GRO ethtool option instead of
LRO.  I've kept the lro module parameter as is since that's for
compatibility only.

I have eliminated efx_rx_mk_skb as the GRO layer can take care
of all packets regardless of whether GRO is enabled or not.

So the only case where we don't call GRO is if the packet checksum
is absent.  This is to keep the behaviour changes of the patch to
a minimum.
