Subject: [PATCH 04/15] ehea: Remove num_tx_qps module option
Date: Thu, 12 May 2011 10:52:17 +1000 [thread overview]
Message-ID: <20110512005622.862264994@samba.org> (raw)
In-Reply-To: 20110512005213.897432612@samba.org
[-- Attachment #1: ehea_5.patch --]
[-- Type: text/plain, Size: 7457 bytes --]
The num_tx_qps module option allows a user to configure a different
number of tx and rx queues. Now the networking stack is multiqueue
aware it makes little sense just to enable the tx queues and not the
rx queues so remove the option.
