	According to drivers/net/bnx2x_main.c bnx2x_init_bp()
can alter LRO:

        /* Set TPA flags */
        if (disable_tpa) {
                bp->flags &= ~TPA_ENABLE_FLAG;
                bp->dev->features &= ~NETIF_F_LRO;
        } else {
                bp->flags |= TPA_ENABLE_FLAG;
                bp->dev->features |= NETIF_F_LRO;
        }

	You probably can disable it as follows:

modprobe bnx2x disable_tpa=1

or in /etc/modprobe.conf:
options bnx2x disable_tpa=1

	For checking the current state you can look at the
module parameters for disable_tpa:

cat /sys/module/<MODULE>/parameters/...
