What I did
Fix fpmsyncd crash when evpn is configured with fib suppression enabled. When protocol is not set, it's value is empty and fpmsyncd throws exception trying to covert to int and exits https://github.com/sonic-net/sonic-swss/blob/04912ad05aab8f4ebc40bcec70f00492a886e2ce/fpmsyncd/routesync.cpp#L1437. Protocol field was not extracted in the evpn flow. Decoding protocol from raw message fixed the issue.
Why I did it
To handle BGP suppress fib and evpn interop
How I verified it
Manually verified the fix. Added UT to cover.
