Subject: [BNX2]: Add delay before reading firmware version.
X-Git-Tag: v2.6.23-rc1~496^2~22
X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=c2d3db8c7cbb94e77461627085b85d74dc64d716;p=linux-2.6-omap-h63xx.git

[BNX2]: Add delay before reading firmware version.

The management firmware may still be loading during bnx2_init_one()
because of the D3hot -> D0 transition and the firmware version may
not be available without waiting a bit.
