bnx2x: Prevent load reordering in tx completion processing This patch fixes an issue seen on Power systems with bnx2x which results in the skb is NULL WARN_ON in bnx2x_free_tx_pkt firing due to the skb pointer getting loaded in bnx2x_free_tx_pkt prior to the hw_cons load in bnx2x_tx_int. Adding a read memory barrier resolves the issue. Signed-off-by: Brian King <brking@linux.vnet.ibm.com> Signed-off-by: David S. Miller <davem@davemloft.net>
