Description
This PR cherrypicks a PR from the Geth upstream. The original description is as follows:
"This PR will allow a previously underpriced transaction back in after a timeout of 5 minutes. This will block most transaction spam but allow for transactions to be re-broadcasted on networks with less transaction flow."
Rationale
Resolves #2084
We have some users saying that underpriced transactions were not able to be broadcast at all. This code change should help resolve that.
