Subject: [PATCH] cxgb4: Fix number of queue sets corssing the limit
Date: Tue, 18 Oct 2016 14:21:25 +0530 [thread overview]
Message-ID: <1476780685-31363-1-git-send-email-ganeshgr@chelsio.com> (raw)
Do not let number of offload queue sets to go more than
MAX_OFLD_QSETS, which would otherwise crash the driver
on machines with cores more than MAX_OFLD_QSETS.
