If anyone has any objections, please let me know. ------------------ From: Andrey Vatoropin commit 7d277a7a58578dd62fd546ddaef459ec24ccae36 upstream. be_insert_vlan_in_pkt() is called with the wrb_params argument being NULL at be_send_pkt_to_bmc() call site.  This may lead to dereferencing a NULL pointer when processing a workaround for specific packet, as commit bc0c3405abbb ("be2net: fix a Tx stall bug caused by a specific ipv6 packet") states. The correct way would be to pass the wrb_params from be_xmit(). Fixes: 760c295e0e8d ("be2net: Support for OS2BMC.")
