Subject: [PATCH 18/25] enic: fix segfault on Tx path after restarting a device
|
|
|
|
If you stop then start a port that had already sent some packets,
|
|
there was a segfault due to not resetting the number of completed
|
|
sends to zero.
|
|
|
|
Fixes: d5d882fe1a11 ("Tx path rewrite to reduce Host CPU overhead")
