Adjust t4_port_init() to work with VF devices.

Authored by jhb on Aug 15 2016, 8:05 PM.



Adjust t4_port_init() to work with VF devices.

Specifically, the FW_PORT_CMD may or may not work for a VF (the PF
driver can choose whether or not to permit access to this command),
so don't attempt to fetch port information on a VF if permission is
denied by the PF.

Test Plan
  • tested with both VF and PF devices in the VF branch

jhb added a reviewer: np.

p->tx_chan is being used before it has been initialized.


Oops, I'll revert that back to 'j'. I had originally moved this below t4_alloc_vi() but had to move it back and this is leftover from that.

np edited edge metadata.

pi->tx_chan/j was the only comment I had, rest looks good.
