[Cerowrt-devel] quick update

[Dave Taht <dave.taht@gmail.com>]

If you can't tell, I have been trying for a stable-ish release of cero
once a month, around the 15th. I'm not sure if I'm going to make it
this time.

Some good things have been happening...

I THINK, but am not sure, the skb shrinkage thing I was doing needs
some headroom added in some cases. I am hoping this would account some
of the introduced flakyness on wifi we encountered in the last dev
release.

This little bit in ath9k/xmit.c looks suspicious:

/* Add the padding after the header if this is not already done */
       padpos = ath9k_cmn_padpos(hdr->frame_control);
       padsize = padpos & 3;
       if (padsize && skb->len > padpos) {
               if (skb_headroom(skb) < padsize)
                       return -ENOMEM;

Also found a few improvements to make to fq_codel at low bandwidths
(below 10Mbit) and something of a theoretical problem with queue
occupancy with tons of flows, and there's been some good threads on
the codel list.

But finding these has been kind of tedious and slow, and my non-bloat,
and trying to make eating money, workload has been a bit much of late.

So I will try to polish up the latest set of cero patches and get them
out there after a great deal more testing on x86.
