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.) Signed-off-by: Ben Hutchings Signed-off-by: David S.

We have not held the link settings in software (aside from flow control), and have relied on asking the hardware what they are. This is a problem because in some cases the hardware may no longer be in a state to tell us. In particular, if an entire multi-port board is reset through one port, the driver bindings to other ports have no chance to save settings before recovering. We only actually need to keep track of the autonegotiation settings, so add an ethtool advertising mask to struct efx_nic, initialise it in PHY init and update it as necessary. Remove now-unneeded uses of efx_phy_op::{get,set}_settings() and struct ethtool_cmd. Much of this was done by Steve Hodgson . Signed-off-by: Ben Hutchings Signed-off-by: David S.
