Subject: enic: set IG desc cache flag in open
Patch-mainline: v4.17-rc1
Git-commit: 5de0c022f1b0bce073cb04dd69ed7982805e5763
References: bsc#1113431

New adapter needs CMD_OPENF_IG_DESCCACHE flag to be set. If this flag is
not set, fw flushes the global IG desc cache. This flag is nop in older
adapter.

Also increment driver version
