Subject: e1000: fix ethtool test irq alloc as "probe"
X-Git-Tag: v2.6.17~35^2^2~1
X-Git-Url: https://openfabrics.org/gitweb/?a=commitdiff_plain;h=b9b6e78b11de295ef073271979355d5fab71b877;p=~shefty%2Frdma-dev.git

e1000: fix ethtool test irq alloc as "probe"

New code added in 2.6.17 caused setup_irq to print a warning when
running ethtool -t eth0 offline.

This test marks the request_irq call made by this test as a "probe"
to see if the interrupt is shared or not.
