gcc 10 issues warnings about the use of rearm_data marker
from struct rte_mbuf.
e.g.
../drivers/net/enic/enic_rxtx_vec_avx2.c: In function ‘rx_one’:
../drivers/net/enic/enic_rxtx_vec_avx2.c:21:2:
warning:
array subscript 0 is outside the bounds of an interior zero-length array
‘RTE_MARKER64’ {aka ‘long unsigned int[0]’} [-Wzero-length-bounds]
21 | *(uint64_t *)&mb->rearm_data = enic->mbuf_initializer;
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~
In file included from ../lib/librte_mbuf/rte_mbuf.h:45,
from ../drivers/net/enic/enic_rxtx_vec_avx2.c:6:
../lib/librte_mbuf/rte_mbuf_core.h:484:15:
note: while referencing ‘rearm_data’
484 | RTE_MARKER64 rearm_data;
|
Disable this warning for gcc 10 in order to allow v20.05 to build
without changes to struct rte_mbuf.
