[Linuxptp-users] Xilinx Ethernet Lite does not support multicast packets

[nicolas l. <nic...@ub...>]

Hello,

"Xilinx Ethernet Lite"  is marked as supporting PHY (and other)
timestamping in the Driver Support Matrix.
But according to data-sheet : "The Ethernet Lite MAC core does not
support multicast packets."

I try to get it working with a DP83640 PHY since three weeks, but
without multicast support I now wonder how this would be possible.
But why the emaclite drivers implements "skb_defer_rx_timestamp(skb)"
function in the "xemaclite_rx_handler()" and
"skb_tx_timestamp(new_skb)"  in   the "xemaclite_send" (
.ndo_start_xmit) if it could not be usable ?
there is something I've missed ?

Thanks

Nicolas
