bxe + if_lagg

2012-10-30 Thread Tom Judge
-BEGIN PGP SIGNED MESSAGE-
Hash: SHA1



I am trying to get if_lagg working in an HP blade for failover between
the 2 in chassis cisco switches, but it would seem that the link state
is not being propagated up to the lagg device.

Any hints/ideas?

Do you need two physical interfaces configured for failover mode to do 
any good?

Forgot to mention this is 9.0-RELEASE.

No, a single interface should set status active:

bce0: flags=8843 metric 0 mtu 1500

options=c01bb
ether 00:1e:0b:c4:00:a2
nd6 options=29

Have you tried ifconfig up'ing the lagg? Shouldn't have to if things were 
functioning properly, but you might have to.

If that works, then assigning an address to the interface or adding an ifconfig 
up in rc.local might workaround the issue.

Cheers,
-Garrett

Nope these don't resolve the issue, its almost like lagg cant see the
link state of the members.

Re: request for help: 'fixing' the 802.11 TX path

2012-10-30 Thread Adrian Chadd
So I cheaped out for now and just wrapped the ath TX path in a new TX only lock.

I'm open to other suggestions about how to make the "queue everything
through a taskqueue" work, but unfortunately it seems that I'm
defeated by the inner workings of the network stack locking and how
that plays with the scheduler.

I even tried experimenting with a second taskqueue just for TX but it
still suffered from much reduced performance.

The annoying thing? Changing the eventtimer to enable
periodic+idletick improved performance as well as flipping
machdep.idle=spin. I thought that stuff was fixed but alas.

So now this is done, I may create a per-VAP TX lock in net80211 in
order to serialise raw and normal net80211 TX; that will fix a lot of
the the serialisation and state issues that creep up. Then it's off to
if_transmit() land.

Thanks everyone,




Adrian
