Enhance get_arp_table and get_mac_address_table with filtering arguments

I ran into this myself not too long ago. Although the API change was approved for NAPALM, there's a limitation in librouteros: it doesn't accept any filter arguments with the print command. I modified librouteros to make it work, but the change broke compatibility with NAPALM, so I ended up just using librouteros by itself. =/ If you're interested, here's my fork with the changes:

Currently librouteros does not have any "official" query support. I am planning to add this. For now I can implement a rather crude workaround.

I am confused. napalm-base have some pull requests but napalm-ros uses napalm which does not have this extended method. @mirceaulinic can you help explaining ?

Closing since napalm-base does not have any filtering.
