Welcome pimd to the Quagga daemon zoo!
This is a merge of commit 77ae369 ("pimd: Log ifindex found for an
interface when zebra lib reports a new connected address."), with
the intermediate "reconnect" changes removed (c9adf00...d274381).
d274381 is replaced with b162ab7, which includes some changes. In
addition, 4 reconnect-related changes and 1 cosmetic one have been
bumped out.
The rebase command used to produce the branch that is merged here is:
git rebase --onto b162ab7 c9adf00 77ae369
Note that 3 patches had their author rewritten from
"Anonymous SR#108542 <>" (which is not a valid git author ID)
to: "Savannah SR#108542 <nbahr@atcorp.com>" (which is the e-mail address
listed in the associated Savannah ticket)
