[PATCH net] cxgb4/cxgb4vf: Allocate more queues for 100G adapter

[PATCH net] cxgb4/cxgb4vf: Allocate more queues for 100G adapter

[Hariprasad Shenai]

We were missing check for 100G while checking port speed, which lead to
less number of queues getting allocated for 100G and leading to low
throughput. Adding the missing check for both NIC and vNIC driver.

Hi David,

I missed 25G, will send a V2 for the same with changes for 25Gbps adapter too.

Thanks,
Hari
