BGP: Handle multiple capabilities in one Optional Parameter #480
Conversation
* Fixes #118 (please see issue for details) * Introduce `capabilities` property (for cases where there are >1 capablity) * Keep older `capability` property for backward compatibility * Added `__bgp10` unittest, which broke the original parser

unused?
also prob shouldn't create new fields inside this method

calling len() on each instance of capability would cause serialization to bytes, then taking the resulting length. would something like sum(cap.len for cap in self.capabilities) achieve the same result?

Alternatively you could override the __len__ method to return that header element?

I believe pep8 would want whitespace around +

This doesn't cover the case where the type is AUTHENTICATION, as capabilities won't exist (and it doesn't count the length of the authentication data).

This will also fail if this is an authentication parameter. Perhaps some variant of caps = bytes(self.data) if not isinstance(self.data, list) else b''.join(map(bytes, self.data))?
