Subject: net/mlx5: revert setting bonding representor to first PF
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=9b03958aebaaa49fb9492b53886653e91667be86;p=dpdk.git

net/mlx5: revert setting bonding representor to first PF

With kernel bonding, representors on second PF are being probed by
devargs:
	<primary_bdf>,representor=pf1vf<N>
No need to save primary PF port ID and lookup when probing sibling
ports, revert patch [1]

commit e6818853c022 ("net/mlx5: set representor to first PF in bonding mode")
