tg3: Minor EEE code tweaks
The first hunk of this patch makes sure that the driver checks for the
appropriate preconditions before checking if EEE negotiation succeeded.
More specifically the link needs to be full duplex for EEE to be
enabled.
The second and third hunks of this patch fix a bug where the eee
advertisement register would be programmed with extra bits set.
The fourth hunk of this patch makes sure the EEE capability flag is not
set for 5718 A0 devices and that the device is not a serdes device.
None of these modifications are strictly necessary. The driver /
hardware still does the right thing. They are submitted primarily for
correctness.

sfc: Fix event based MCDI completion and MC REBOOT/CMDDONE ordering issue
The mcfw *never* sends CMDDONE when rebooting. Changing this so that it always
sends CMDDONE *before* REBOOT is easy on Siena, but it's not obvious that we
could guarantee to be able to implement this on future hardware.
Given this, I'm less convinced that the protocol should be changed.
To reiterate the failure mode: The driver sees this:
issue command
receive REBOOT event
Was that reboot event sent before the command was issued, or in
response to the command? If the former then there will be a subsequent
CMDDONE event, if the latter, then there will be no CMDDONE event.
Options to resolve this are:
1. REBOOT always completes an outstanding mcdi request, and we set
the credits count to ignore a subsequent CMDDONE event with
mismatching seqno.
2. REBOOT never completes an outstanding mcdi request. If there is
no CMDDONE event then we rely on the mcdi timeout code to complete
the outstanding request, incurring a 10s delay.
I'd argue that (2) is tidier, but that incurring a 10s delay is a little
needless. Let's go with (1).
