The required module-build bits were originally identified in the
upstream pull request: https://github.com/openzfs/zfs/pull/12735
But were missed when the code was imported (since they are not
committed upstream).

Previously we added ack-war prevention for misbehaving firewalls. This is
where the f/w or nat messes up its sequence numbers and causes an ack-war.
There is yet another type of ack war that we have found in the wild that is
like unto this. Basically the f/w or nat gets a ack (keep-alive probe or such)
and instead of turning the ack/seq around and adding a TH_RST it does something
real stupid and sends a new packet with seq=0. This of course triggers the challenge
ack in the reset processing which then sends in a challenge ack (if the seq=0 is within
the range of possible sequence numbers allowed by the challenge) and then we rinse-repeat.

This will add the needed tweaks (similar to the last ack-war prevention using the same sysctls and counters)
to prevent it and allow say 5 per second by default.

Commit dae1713419a6 did not add two required lines for edonr specific
functionality to this file, causing kernel build failures if ZFS is
compiled in.

This commit should be included in an eventual MFC of dae1713419a6.

Since vfs.nfsd.srvmaxio can only be set when nfsd.ko
is loaded, but nfsd is not running, setting it in
/etc/sysctl.conf is not feasible when "options NFSD"
was not specified for the kernel.

This patch adds a new rc variable nfs_server_maxio,
which sets vfs.nfsd.srvmaxio at the correct time.

rc.conf.5 will be patched separately.

making sure that all the mips things build before decommissioning it and
this is the only thing that's broken...
