> The ixgbe driver does not compile if CONFIG_RTE_IXGBE_RX_OLFLAGS_ENABLE=n
> because the macro has not the proper number of parameters. To reproduce
> the issue:
>
> make config T=x86_64-native-linuxapp-gcc
> sed -i 's,CONFIG_RTE_IXGBE_RX_OLFLAGS_ENABLE=y,CONFIG_RTE_IXGBE_RX_OLFLAGS_ENABLE=n,' build/.config
> make -j4
> [...]

> ixgbe_rxtx_vec_sse.c:345:53: error: macro "desc_to_olflags_v" passed 3 arguments, but takes just 2
> desc_to_olflags_v(descs, vlan_flags, &rx_pkts[pos]);
> ^
> ixgbe_rxtx_vec_sse.c:345:3: error: ‘desc_to_olflags_v’ undeclared (first use in this function)

> ^
> ixgbe_rxtx_vec_sse.c:345:3: note: each undeclared identifier is reported only once for each function it appears in
> ixgbe_rxtx_vec_sse.c:231:10: error: variable ‘vlan_flags’ set but not used [-Werror=unused-but-set-variable]
> uint8_t vlan_flags;
> ^
> cc1: all warnings being treated as errors
>
> This patch fixes the number of arguments in th macro, and ensure that
> vlan_flags is marked as used to avoid the third error.
