enic: fix warnings
A lot of warnings were not seen because $(WERROR_FLAGS) was not set in the Makefile. But they appear with toolchains that enforce more checks. -Wno-deprecated seems useless. -Wno-strict-aliasing is added to avoid false positives. This patch cleans up unused variable, unused functions, wrong types, static declarations, etc. A lot of functions have unused parameters; it suggests that more clean-up could be needed. Signed-off-by: Thomas Monjalon <thomas.monjalon@6wind.com> Acked-by: Sujith Sankar <ssujith@cisco.com>
