    sys/dev/netif/bge    if_bge.c if_bgereg.h 
  Log:
  For PCI Express devices:
  1) Adjust max read request size to 4Kbytes
  2) Turn on FIFO_LONG_BURST in RDMA during bge_blockinit()
  
  Though 1) does not seem to have much to do with the poor TX performance (*)
  observed on PCI Express bge(4), 2) does fix the problem.
