[ Upstream commit 3ffcd7b657c9d96eb3ffe174449b4248dd7fc6a9 ]
The Get Tx Topology AQ command (opcode 0x0418) has different read flag requirements depending on the hardware/firmware. For E810, E822, and E823 firmware the read flag must be set, and for newer hardware (E825 and E830) it must not be set.
This results in failure to configure Tx topology and the following warning message during probe:
DDP package does not support Tx scheduling layers switching feature - please update to the latest DDP package and try again
The current implementation only handles E825-C but not E830. It is confusing as we first check ice_is_e825c() and then set the flag in the set case. Finally, we check ice_is_e825c() again and set the flag for all other hardware in both the set and get case.
Instead, notice that we always need the read flag for set, but only need the read flag for get on E810, E822, and E823 firmware. Fix the logic to check the MAC type and set the read flag in get only on the older devices which require it.
