  sfc: Poll for MCDI completion once before timeout occurs (2013-12-06 22:27:55 +0000)

Several fixes for the PTP hardware support added in 3.7:
1. Fix filtering of PTP packets on the TX path to be robust against bad
header lengths.
2. Limit logging on the RX path in case of a PTP packet flood, partly
from Laurence Evans.
3. Disable PTP hardware when the interface is down so that we don't
receive RX timestamp events, from Alexandre Rames.
4. Maintain clock frequency adjustment when a time offset is applied.

Also fixes for the SFC9100 family support added in 3.12:
5. Take the RX prefix length into account when applying NET_IP_ALIGN,
from Andrew Rybchenko.
6. Work around a bug that breaks communication between the driver and
firmware, from Robert Stonehouse.

Please also queue these up for the appropriate stable branches.

Ben.
