Subject: [net-next PATCH 03/26] igb: move initialization of number of queues into set_interrupt_capability
Date: Sat, 07 Feb 2009 01:15:45 -0800	[thread overview]
Message-ID: <20090207091544.15697.99817.stgit@lost.foo-projects.org> (raw)
In-Reply-To: <20090207091504.15697.26667.stgit@lost.foo-projects.org>

From: Alexander Duyck <alexander.h.duyck@intel.com>

This patch moves the initialization of the number of queues into
set_interrupt_capability.  This allows the number of queues to increase in
the unlikely event that the system initially fails to allocate enough msi-x
interrupts, does a suspend/resume, and then can allocate enough interrupts
on resume.
