The Linux kernel only offloads the TCP and UDP -checksums (and always performs the pseudo header checksums), so -the driver only supports checksumming for TCP/IP and UDP/IP -packets. Use ethtool to enable or disable this feature for RX -and TX. - -VLAN - -In order to use VLAN, please consult Linux documentation on -configuring VLANs. The gianfar driver supports hardware insertion and -extraction of VLAN headers, but not filtering. Filtering will be -done by the kernel. - -MULTICASTING - -The gianfar driver supports using the group hash table on the -TSEC (and the extended hash table on the eTSEC) for multicast -filtering. On the eTSEC, the exact-match MAC registers are used -before the hash tables. See Linux documentation on how to join -multicast groups. - -PADDING - -The gianfar driver supports padding received frames with 2 bytes -to align the IP header to a 16-byte boundary, when supported by -hardware. - -ETHTOOL - -The gianfar driver supports the use of ethtool for many -configuration options. You must run ethtool only on currently -open interfaces. See ethtool documentation for details. |
