sk_buff unmap_array grows greater than 65536 (x2) with Tx ring of 65536. Reducing TXQ depth and safe(max) acking of Tx events to 32768 (same as Rx). Add defines for TX and RX queue depths.
I was happy at the 'reducing txq depth' portion of the email, then I saw the value it was reduced to. thx for commenting thusly...
BNAD_MAX_Q_DEPTH is now defined but not used. BTW, 32768 slots in a RX queue is insane.
