From: John Daley Date: Fri, 3 Jun 2016 00:22:49 +0000 (-0700) Subject: net/enic: remove unused functions in Tx path X-Git-Tag: spdx-start~6543 X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=d309bdc2c9518a1844948e4248bbee9fd0b0a672;p=dpdk.git net/enic: remove unused functions in Tx path Functions existed which were never called. Removed them. Also rename the 'pmd' from the name of the Tx function to improve clarity.
