Browse Source 
- Remove restriction to allow multicast addresses to be added to byp_lut
and sci_lut
- Also update the usage of macsec_enable node to enable/disable both Tx
and Rx traffic
- Fix the issue of generating same Hkey for differet SAK by moving the Hey
key generation logic post obtaining SAK
