Akhil Goyal June 8, 2023, 6:54 a.m. UTC 
  Added Packet number threshold parameter in MACsec SC
configuration to identify the maximum allowed threshold
for packet number field in the packet.
A field is_xpn is also added to identify if the SAs are
configured for extended packet number or not so that
packet number threshold can be configured accordingly.
