Subject: [dpdk-dev] [PATCH v2] net/ixgbe: fix compilation when offload flags disabled
Date: Fri, 1 Jul 2016 10:02:27 +0200 [thread overview]
Message-ID: <1467360147-19571-1-git-send-email-olivier.matz@6wind.com> (raw)
In-Reply-To: <1467042269-22703-1-git-send-email-olivier.matz@6wind.com>
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: In function ‘_recv_raw_pkts_vec’:
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)
desc_to_olflags_v(descs, vlan_flags, &rx_pkts[pos]);
^
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.
Fixes: b37b528d957c ("mbuf: add new Rx flags for stripped VLAN")
