[Bug 273152] cxgbe: panic in sousrsend() after enabling "toe"

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=273152

--- Comment #1 from Greg Becker <greg@codeconcepts.com> ---
See referenced ticket (272947) for details, but the solution here to avoid the
panic is to load t4_tom as a module after boot (e.g., via rc.conf before
configuring the interface).  That's seems awfully brittle, is this something
that's fixable and/or worth fixing?

Regardless, with that workaround in place, there is a follow-on problem in that
mounting an NFS file system over cc0 with toe enabled and then running a simple
"find /mntpt" results in a hang/stall, where it prints about 150 files then
stalls for a very long time, then repeats the print+hang cycle until it's done.
I see this on both 13.2-RELEASE and 14.0-CURRENT.

Note that the find command runs as expected without any delays if toe is not
enabled.

Should I open a different ticket for the NFS hang/stall problem?
