enic: fix last packet not being sent
|
|
|
|
|
|
|
|
|
|
The last packet of the tx burst function array was not being
|
|
|
|
|
emitted until the subsequent call. The nic descriptor index
|
|
|
|
|
was being set to the current tx descriptor instead of one past
|
|
|
|
|
the descriptor as required by the nic.
|
|
|
|
|
|
|
|
|
|
Fixes: d739ba4c6abf ("enic: improve Tx packet rate")
