net: packet: pass on redundant net info in packet_recvmsg

This patch extends the skb shared info to include the
redundant network information from packets sent/received in
HSR/PRP networks. The redundant information includes
information from the HSR TAG, PRP RCT and the redundant port
on which the packet is sent/received.

Redundant network information (HSR TAG or PRP RCT) saved in skb
shared info struct is passed to user space application through
control message area of the receive message struct.
