This is what I get and these are probably the statements of interest:

hw.ixl.enable_tx_fc_filter: 1
dev.em.0.fc_low_water: 20552
dev.em.0.fc_high_water: 23584

what would be the correct setting for disabling flow control with a Realtek driver?
hw.igb.0.fc=0 is for Intel as I understand.

my Nic cards show up as em0 and re0

thanks,
