qeth: add layer 2 RX/TX checksum offloading
Checksum offloading for send and receive is already
supported for layer 3 (IP layer). This patch
adds support for RX and TX hardware checksum offloading
for layer 2 (MAC layer). The hardware calculates the checksum
for IP UDP and TCP packets.
This patch moves the hardware checksum offloading setup
to the set of common functions in qeth_core_main.c.
Layer 2 and layer 3 now simply call the same common functions.
Also note that TX checksum offloading is always enabled.
The device driver relies on the TCP/IP stack to make use of
this feature.
