6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: MD Danish Anwar <danishanwar@xxxxxx>
[ 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().
Fixes: e9b4ece7d74b ("net: ti: icssg-prueth: Add Firmware config and classification APIs.")
