qed: QL41xxx VF MSI-x table

Browse source

The QL41xxx adapters' PCI allows a single configuration for the
MSI-x table size of all child VFs of a given PF.
The existing code wouldn't cause the management firmware to set
that value, meaning the VFs would retain the default MSI-x table
size.

Introduce a new scheme so that whenever a VF is enabled, driver
would set the number of MSI-x to be the maximum over the various
VFs' needs.
