[dpdk-dev] [PATCH] net/mrvl: reset errno before library call

[Tomasz Duszynski]

In case errno contains some non-zero value and call to strtoul() is
successful -2 error will be returned.

Setting errno to zero before calling strtoul() makes sure
errors will be handled correctly.

Fixes: 0ddc9b815b11 ("net/mrvl: add net PMD skeleton")
