AI points out that the DMA map etc. path does not obey the new
kick_prod that you're adding. TBH the checks you're adding look
quite messy. You should try to fix this by centralizing the kick /
flush logic at the end of bnxt_start_xmit() ? 
Maybe bnxt_sw_udp_gso_xmit() should be returning int 1/0/-1 that
you can then interpret in the caller instead or some such.
