- TX completions are worth 1 point
- RX completions are worth 4 if merged using LRO or 2 otherwise

of 5 us. Increase moderation if the score is more than 20000, up to

In rare cases, reading the legacy interrupt status register can
acknowledge an event queue whose attention flag has not yet been set
in the register. Until we service this event queue it will not
generate any more interrupts. Therefore, as a secondary check, poll
the next slot in each active event queue whose flag is not set.

When flushing queues we disable normal interrupt and event handling and
poll event queue 0 looking for flush completions. Unfortunately the
flush event polling loop fails to move past any other type of event.
This problem has not been observed in production hardware but appears to
be a possibility.

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.

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.

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.
