Subject: [PATCH 2/3] net: xilinx: axienet: Enable NETIF_F_HW_CSUM for partial tx checksumming

Partial tx chechsumming is completely generic and does not depend on the
L3/L4 protocol. Signal this to the net subsystem by enabling the
more-generic offload feature (instead of restricting ourselves to
TCP/UDP over IPv4 checksumming only like is necessary with full
checksumming).
