Subject: [PATCH 1/8] netxen: fix tx csum status

From: Sucheta Chakraborty <sucheta.chakraborty@...gic.com>

Kernel default tx csum function (ethtool_op_get_tx_csum) doesn't show
correct csum status. It takes various FLAGS (NETIF_F_ALL_CSUM) in account
to show tx csum status, which driver doesn't set while disabling tx csum.
