Summary

When the inpcb route cache is invalidated after a change to the
routing tables, we need to invalidate the LLE cache as well.
Previous to this change packets for the connection would continue
to use the old L2 information from the old L3 gateway, and the
packets for the connection would likely be blackholed.

Could this use the new invalidate macro?

Could this use the new invalidate macro?

I realized after uploading that I presented this reviews in a confusing order. First I added this change in one review, then in the second review I replaced this immediately with the invalidate macro. Sorry about that, but yes, the invalidate macro can be used here and I did make that change in the other review.

Got it. I didn't realize it, but Phabricator lists the reviews in reverse order, so that's the order I looked at them.
