[dpdk-dev] [PATCH 36/38] net/sfc: use switch port ID as representor ID

[Andrew Rybchenko]

From: Viacheslav Galaktionov <viacheslav.galaktionov at oktetlabs.ru>

Representor IDs must be unique for each representor. VFs, which are
currently used, are not unique as they may repeat in combination with
different PCI controllers and PFs. On the other hand, switch port IDs
are unique, so they are a better fit for this role.
