stable inclusion from stable-v6.6.33 commit 75bc6bc559b93a620f6c690adc3a5d91c9dd60e8 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IAD6H2
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=...
--------------------------------
[ Upstream commit 56a5cf538c3f2d935b0d81040a8303b6e7fc5fd8 ]
The start counter for FT1 filter is wrongly set to 0 in the driver. FT1 is used for source address violation (SAV) check and source address starts at Byte 6 not Byte 0. Fix this by changing start counter to ETH_ALEN in icssg_ft1_set_mac_addr().
