[PATCH AUTOSEL 6.12 057/107] net: stmmac: Programming sequence for VLAN packets with split header

[Sasha Levin]

From: Abhishek Chauhan <quic_abchauha@quicinc.com>

[ Upstream commit d10f1a4e44c3bf874701f86f8cc43490e1956acf ]

Currently reset state configuration of split header works fine for
non-tagged packets and we see no corruption in payload of any size

We need additional programming sequence with reset configuration to
handle VLAN tagged packets to avoid corruption in payload for packets
of size greater than 256 bytes.

Without this change ping application complains about corruption
in payload when the size of the VLAN packet exceeds 256 bytes.

With this change tagged and non-tagged packets of any size works fine
and there is no corruption seen.

Current configuration which has the issue for VLAN packet
----------------------------------------------------------

Split happens at the position at Layer 3 header
|MAC-DA|MAC-SA|Vlan Tag|Ether type|IP header|IP data|Rest of the payload|
                         2 bytes            ^
                                            |

With the fix we are making sure that the split happens now at
Layer 2 which is end of ethernet header and start of IP payload

Ip traffic split
-----------------

Bits which take care of this are SPLM and SPLOFST
SPLM = Split mode is set to Layer 2
SPLOFST = These bits indicate the value of offset from the beginning
of Length/Type field at which header split should take place when the
appropriate SPLM is selected. Reset value is 2bytes.

Un-tagged data (without VLAN)
|MAC-DA|MAC-SA|Ether type|IP header|IP data|Rest of the payload|
                  2bytes ^
			 |

Tagged data (with VLAN)
|MAC-DA|MAC-SA|VLAN Tag|Ether type|IP header|IP data|Rest of the payload|
                          2bytes  ^
				  |

Non-IP traffic split such AV packet
------------------------------------

Bits which take care of this are
SAVE = Split AV Enable
SAVO = Split AV Offset, similar to SPLOFST but this is for AVTP
packets.

|Preamble|MAC-DA|MAC-SA|VLAN tag|Ether type|IEEE 1722 payload|CRC|
				    2bytes ^
					   |
