Subject: [PATCHv2 net-next 1/3] net: Add provision to specify pf number while assigning VF mac
Chelsio T4/T5 cards have SR-IOV Capabilities on Physical Functions
0..3 and the administrative Driver(cxgb4) attaches to Physical Function 4.
Each of the Physical Functions 0..3 can support up to 16 Virtual
Functions. With the current Linux APIs, a 2-Port card would only be
able to use the Virtual Functions on Physical Functions 0..1 and not
allow the Virtual Functions on Physical Functions 2..3 to be used since
there are no Ports 2..3 on a 2-Port card.
Also the current ip commands takes netdev as one of the argument, and
it assumes a 1-to-1 mapping of Network Ports, Physical Functions and the
SR-IOV Virtual Functions of those Physical Functions. But it is not
true in our case and won't work for us.
Added a new argument to specify the PF number associated with the VF, to
fix this.
