Wonder if the netmap issues lies with a buffer size issue between the re driver and netmap?
The re driver sets a buffer to the highest supported mtu size by the nic. Probably 9000 on a gigabit card. It is override or by setting hw.re.max_rx_mbuf_sz to something like 2048 or 4096.
I’ve seen several mentions that netmap does not do well with a buffer size greater than 4096.
Does anyone have more information on this?
