1475 | * We have the following requirements for issuing firmware commands: | |
1476 | * - Some commands require that the packet transmit path is idle when | |
1477 | * the command is issued. (For simplicity, we'll just quiesce the | |
1478 | * transmit path for every command.) | |
1479 | * - There are certain sequences of commands that need to be issued to | |
1480 | * the hardware sequentially, with no other intervening commands. | |
1481 | * | |
1482 | * This leads to an implementation of a "firmware lock" as a mutex that | |
1483 | * can be taken recursively, and which is taken by both the low-level | |
1484 | * command submission function (mwl8k_post_cmd) as well as any users of | |
1485 | * that function that require issuing of an atomic sequence of commands, | |
1486 | * and quiesces the transmit path whenever it's taken. | |
