Subject: [PATCH net v2 0/3] net: ipa: fix two replenish bugs
This series contains two fixes for bugs in the IPA receive buffer
replenishing code. The (new) second patch defines a bitmap to
represent endpoint the replenish enabled flag. Its purpose is to
prepare for the third patch, which adds an additional flag.
Version 2 of this series uses bitmap operations in the second bug
fix rather than an atomic variable, as suggested by Jakub.
