sfc: Simplify XMAC link polling
From: Steve Hodgson <shodgson@solarflare.com>
Only the XMAC on Falcon needs help from the driver to poll and reset
the MAC-PHY link (XAUI); GMII is a simple parallel bus and on later
NICs firmware takes care of the XAUI link. Also, an XMAC interrupt
currently schedules a work item which simply clears a flag
(efx_nic::mac_up) to be checked by the regular monitor (or the next
link reconfiguration, if that is sooner).
Rename the flag to xmac_poll_required, changing its sense. Remove the
needless indirection and just set the flag immediately. Call
falcon_xmac_poll() directly where required.
Add a new generic operation mac_op::check_fault to check the link
outside of regular monitoring, as required during self-tests.
(Note that this leaves us with an unused work item, but we will
immediately have another use for it.)
