I would be grateful if you could make patch.

I had wanted to remove the larger cluster sizes from the driver a
while back, but for reasons
I don't remember that code change didn't happen. The new 40G ixl
driver does this, it only
uses standard clusters for anything under 2K, and above that
everything uses 4K.
I would be curious to see if this change would resolve your problem,
would you like a patch,
or are you able to hack the code yourself to do this?

Hi All.
I have a server with two Intel 10G NIC. OS FreeBSD
10.1-Release amd64. Server works like NFS, samba-server and
iSCSI target. Both NICs aggregated into lagg device and set
MTU 9014 to them. There are some tuning sysctl.conf:
kern.maxfiles=6289601
kern.maxfilesperproc=5660640
kern.maxvnodes=3339565

net.inet.tcp.sendspace=65536
net.inet.tcp.recvbuf_max=16777216
net.inet.tcp.recvspace=65536
After some days of working, the errors are appearing:
ix1: Interface stopped DISTRIBUTING, possible flapping
ix0: Interface stopped DISTRIBUTING, possible flapping
ix0: Could not setup receive structures

Hello. It looks like
https://lists.freebsd.org/pipermail/freebsd-net/2014-May/038630.html
is relevant here.
After that errors the NICs stoped working. netstat -m shows:

9k jumbo clusters max is too big, but looks like system cannot
allocate them. There are huge number of "9k requests for jumbo
clusters denied". ifconfig ix down/up don't helped, reboot is
needed. Thanks for any help!
