Subject[PATCH 4.4 61/78] scsi: cxgb4i: fix Tx skb leak
Date
4.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Varun Prakash <varun@chelsio.com>


[ Upstream commit 9b3a081fb62158b50bcc90522ca2423017544367 ]

In case of connection reset Tx skb queue can have some skbs which are
not transmitted so purge Tx skb queue in release_offload_resources() to
avoid skb leak.
