Subject: Re: qmgr for ixp4xx

Hi.

Complementing the previous mail.

I have implemented 64 queues for ixp4xx (following Karl's patch).

My idea was to use queues 32-39 for my eight txreadyq.

As rxq and txreadyq from ethernet in NPEB and NPEC conflict with the
queues in the ixp4xx_hss driver, I have decided to use queues 40-43
for them. Solving a problem with qmgr_stat_overflow, I have been able
to configure the interface (ethernet in NPEB). However not even a ping
can be sent.

Thinking that the problem was using >= 32 queues, I decided to use
queues 23-26... With the same result. So queues 3, 4, 20 and 21 seem
to be fixed for ethernet. But they are also used for HSS!!!

Any ideas?

Miguel Ángel
