sys/dev/pci : if_bnxreg.h if_bnx.c
Log message:
replace arrays of dmamaps and mbuf pointers used to manage packets
on the tx rings (one mbuf ptr/dmamap array entry was created for
every tx descriptor slot at attach time) with a dynamically grown
list of mbuf pointers and dmamaps.
bnx used to have 512 dmamaps/mbuf pointers for the tx ring, now my
system is running with 8 under moderate load.
the big bonus from this is that the dmamap handling is greatly
simplified.
