====================
net/smc: fixes 2020-07-20

Please apply the following patch series for smc to netdev's net tree.

Patch 1 fixes a problem with a buffer that is not put back when the
connection was killed in the meantime.
Patch 2 fixes a wrong behaviour when the maximum dmb buffer count
exceeded.
