bna: TX Path and RX Path Changes
Change details:
- Add bnad_pci_unmap_skb() API to unmap skb from transmit path and update the
unmap index. Add more checks for illegal skbs in transmit path. Add tx_skb
counters for dropped skbs.
- The unmap_cons index used in bnad_free_txbufs() is incorrectly declared as
u16. It quickly wraps around and accesses null sk_buff ptr. So using u32 to
handle unmap_array.
- Disable and enable interrupts from the same polling context to prevent
reordering in Rx path.
- Add Rx NAPI debug counters.
- Make NAPI budget check more generic.
- Modify dim timer stop logic to make it dependent on cfg and run flags
- Handle reduced MSI-X vectors case in bnad_enable_msix.
- Check for single frame TSO skbs and send them out as non-TSO.
- Put memory barrier after bna_txq_prod_indx_doorbell().
