Subject: [PATCH net] net: ti: icssg-prueth: Fix start counter for ft1 filter

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 6 in
icssg_ft1_set_mac_addr().

Fixes: e9b4ece7d74b ("net: ti: icssg-prueth: Add Firmware config and classification APIs.")
