  From: Stephen Hemminger <stephen@networkplumber.org>

This driver defines lots of functions (like init_rss) which are intended
to only be used in this device. But when doing static linking these
global functions cause link failures when similar function name is
used in application.

This patch prefixes all functions defined in cxgbe.h with cxgbe_
to avoid these kind of conflicts.

Fixes: bfcb257d3014 ("net/cxgbe: enable RSS for VF")
Cc: stable@dpdk.org

v2:
* ``init_rspq`` converted into static function instead of prefixing it.
