Squashed backup commit (no shallow-clone history issues) of xiaomi-mt6833-dev/kernel_xiaomi_mt6833 (lineage-23.2 branch, upstream commit 9eece662e) plus all fixes applied to get everpal_defconfig building clean against a modern (GCC 15.2.0) toolchain -- see the previous commit message on the lineage-23.2 branch (also in this repo history is not available here since this is a squashed snapshot; full incremental history lives in the local DL380 checkout and the upstream GitHub remote).

CHECKSUM OFFLOADING
|
|
|
|
The eTSEC controller (first included in parts from late 2005 like
|
|
the 8548) has the ability to perform TCP, UDP, and IP checksums
|
|
in hardware. 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.
