I believe I fixed the buffer sizing with:
* 12e8addd320df995bfb2b00f51c233541f741ae4
* 6987c47569b377f4b6eba9966afdedfb1b39fca8

The MJUM9BYTES thing has been disabled for a long time
* bc408c7d61bdb1ec5df9888299a750b71054644f

Going to close this as fixed.

(In reply to Mike Andrews from comment #2)

I don't know the patch resolves the problems originally reported in this PR.
82574L is very slow, but "netstat -m" shows "0/0/0 requests for jumbo clusters
denied" with/without the patch. 

At least, PBA and high/low-water setting for I21[789] is broken because of 
receive buffer size is too small to save JUMBO frames. PBA should be calculated
from MTU, and high/low-water should be calculated from PBA instead of loading
immediate values, I think.

Dusting this old one off because it's still an issue.

This recent commit looks like, from the description anyway (haven't tested),
that it might fix the issue:

Created attachment 183084
  --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=183084&action=edit
a patch for jumbo frame and others

I don't have a trouble denied some packets temporarily but a trouble dropped
many packets with jumbo frames. I use 12-current with a similar patch attached
this comment, and the patch does not make everything correct but makes
better condition.

I have three devices, 82574L, I217-V, I218-V. I don't have any trouble for
I21[78] regardless with or without the patch when mtu is 1500.
With 9k jumbo, without the patch, scp speed is very slow and
dev.em.0.rx_overruns increases.

On 82574L, dev.em.0.rx_overruns increases without the patch and
dev.em.0.mac_stats.recv_no_buff increases with the patch.
Above 6k jumbo, scp speed is almost 10kB/s without the patch
and the speed is about 10MB/s with the patch.
