4 Subject: [PATCH 12/22] enic: fix last packet not being sent
6 The last packet of the tx burst function array was not being
7 emitted until the subsequent call. The nic descriptor index
8 was being set to the current tx descriptor instead of one past
9 the descriptor as required by the nic.
11 Fixes: d739ba4c6abf ("enic: improve Tx packet rate")
