ibmveth: Implement multi queue on xmit

Browse source

The `ndo_start_xmit` function is protected by a spinlock on the tx queue
being used to transmit the skb. Allow concurrent calls to
`ndo_start_xmit` by using more than one tx queue. This allows for
greater throughput when several jobs are trying to transmit data.

Introduce 16 tx queues (leave single rx queue as is) which each
correspond to one DMA mapped long term buffer.
