The following error popped when compiling with -pedantic:
In file included from
drivers/net/mlx5/mlx5_flow_dv.c:28:0:
include/rte_gre.h:20:2:
error: type of bit-field 'res2' is a GCC extension [-Werror=pedantic]
uint16_t res2:4; /**< Reserved */
Fixing by adding the __extension__ attribute.
Fixes: 894f71a3805d ("net: add GRE header structure")
