This causes build error with gcc 7.1.1 :
...dpdk/drivers/net/i40e/i40e_flow.c:2357:2:
error: ‘memset’ used with length equal to number of elements without
multiplication by element size [-Werror=memset-elt-size]
memset(off_arr, 0, I40E_MAX_FLXPLD_FIED);
^~~~~~
...dpdk/drivers/net/i40e/i40e_flow.c:2358:2:
error: ‘memset’ used with length equal to number of elements without
multiplication by element size [-Werror=memset-elt-size]
memset(len_arr, 0, I40E_MAX_FLXPLD_FIED);
^~~~~~
Fixed by providing correct size to memset.

This code introduced for this release, so fix can be squashed into

That's a fine workaround, therefore:
Acked-by: Adrien Mazarguil <adrien.mazarguil@6wind.com>
On a personal note though, GCC, seriously? While I understand missing breaks
inside switch statements is a common mistake, having the compiler rely on a
comment that basically says "yes, it's done on purpose" just doesn't feel
right; compilers should discard comments and not attempt to interpret them,
otherwise they have to deal with locale-related issues. It's like enforcing
checkpatch.pl rules in GCC by default. Anyway, back to work.
