7	CHECKSUM OFFLOADING
8	
9	The eTSEC controller (first included in parts from late 2005 like
10	the 8548) has the ability to perform TCP, UDP, and IP checksums
11	in hardware.  The Linux kernel only offloads the TCP and UDP
12	checksums (and always performs the pseudo header checksums), so
13	the driver only supports checksumming for TCP/IP and UDP/IP
14	packets.  Use ethtool to enable or disable this feature for RX
15	and TX.

17	VLAN
18	
19	In order to use VLAN, please consult Linux documentation on
20	configuring VLANs.  The gianfar driver supports hardware insertion and
21	extraction of VLAN headers, but not filtering.  Filtering will be
22	done by the kernel.
23	
24	MULTICASTING
25	
26	The gianfar driver supports using the group hash table on the
27	TSEC (and the extended hash table on the eTSEC) for multicast
28	filtering.  On the eTSEC, the exact-match MAC registers are used
29	before the hash tables.  See Linux documentation on how to join
30	multicast groups.
31	
32	PADDING
33	
34	The gianfar driver supports padding received frames with 2 bytes
35	to align the IP header to a 16-byte boundary, when supported by
36	hardware.
37	
38	ETHTOOL
39	
40	The gianfar driver supports the use of ethtool for many
41	configuration options.  You must run ethtool only on currently
42	open interfaces.  See ethtool documentation for details.
