Subject: RDMA/cxgb4: Abort connections when moving to ERROR state
X-Git-Tag: v3.9-rc1~72^2^2~11
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=91e9c07195032bbde47489b8b423053cff5f413d;p=platform%2Fkernel%2Flinux-exynos.git

RDMA/cxgb4: Abort connections when moving to ERROR state

Also, if we ABORT due to unexpected STREAMING data, then wake up
anybody blocked in FINI...
