3.12-stable review patch. If anyone has any objections, please let me know.
------------------ From: Ben Hutchings <[email protected]> [ Upstream commit 35f9a7a380728a94d417e5824a866f969423ac83 ] In case of a flood of PTP packets, the timestamp peripheral and MC firmware on the SFN[56]322F boards may not be able to provide timestamp events for all packets. Don't complain too much about this. Fixes: 7c236c43b838 ('sfc: Add support for IEEE-1588 PTP') Signed-off-by: Ben Hutchings <[email protected]> Signed-off-by: David S.
