[PATCH 1/2] net/nfp: fix representor name too long

[Chaoyong He]

From: Long Wu <long...@corigine.com>

The length of representor name may exceed the limit when we use
it to create rte_ring, so we reduce the length of its name.

For example:
old: 0000:af:00.0_fl_repr_p1
new: af:00.0_repr_p1

Fixes: 2003cb447aa5 ("net/nfp: fix representor creation")
Cc: sta...@dpdk.org
