| 93 | * - The tx frame is already encrypted - don't attempt encryption. |
| 94 | * - The tx frame is a segment of a TCP jumbo frame. |
| 95 | * - This tx frame should not be unmapped and freed by the txrx layer |
| 96 | * after transmission, but instead given to a registered tx completion |
| 97 | * callback. |
