[PATCH V3 net 0/3] There are some bugfix for hibmcge ethernet driver

Posted by Jijie Shao 1 month, 4 weeks ago

This patch set is intended to fix several issues for hibmcge driver:
1. Holding the rtnl_lock in pci_error_handlers->reset_prepare()
   may lead to a deadlock issue.
   2. A division by zero issue caused by debugfs when the port is down.
   3. A probabilistic false positive issue with np_link_fail.
