Merge branch 'net-smc-fixes'
Ursula Braun says: ==================== net/smc: fixes 2018-02-28 here are 3 smc bug fixes for the net-tree. Karsten's first patch is the reworked version of last week's "[PATCH net-next 2/5] net/smc: fix structure size" patch, now solved without using __packed, and now targetted for net instead of net-next. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
