Subject: [net-next 03/12] ixgbe: no need for ipsec csum feature check

From: Shannon Nelson <shannon.nelson@...cle.com>

With the patch
commit f8aa2696b4af ("esp: check the NETIF_F_HW_ESP_TX_CSUM bit before segmenting")
we no longer need to protect ourself from checksum
offload requests on IPsec packets, so we can remove
the check in our .ndo_features_check callback.
