X-Git-Tag: v2.6.28-rc5~61^2^4~2
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=fe25c56190bbc0951d7c53b4ccd148e669d69938;p=pandora-kernel.git

IPoIB: Don't enable NAPI when it's already enabled

If a P_Key is not present when an interface is created, ipoib_open()
will return after doing napi_enable().  ipoib_open() will be called
again from ipoib_pkey_poll() when the P_Key appears, after NAPI has
already been enabled, and try to enable it again. This triggers a
BUG_ON() in napi_enable().

Fix this by moving the call to napi_enable() to after the test for
P_Key presence.
