Subject: [PATCH v2 4/16][BNX2]: Fix race conditions when calling register_netdev().
Date: Thu, 03 May 2007 00:29:06 -0700 [thread overview]
Message-ID: <1178177347.4909.68.camel@dell> (raw)
In-Reply-To: <1178068303.4820.35.camel@dell>
[BNX2]: Fix race conditions when calling register_netdev().
Hot-plug scripts can call bnx2_open() as soon as register_netdev() is
called in bnx2_init_one(). We need to call pci_set_drvdata() and
setup everything before calling register_netdev(). netif_carrier_off()
also needs to be moved to bnx2_open() to avoid race conditions with
the irq.
