Indeed. Permitting this leads to warnings later.
We need to set the tx rate to fixed at a single rate, e.g.,
54M/48M/36M... for a test case.
I do not want a clear error message, I want to the 54M rate pass/set
success to lower wlan driver.
Then lower wlan driver can handle it.
No, that will not happen. You should configure your test AP to actually
support 54M.
Yes, the AP support 54M, but it is not basic rate, so
ieee80211_set_bitrate_mask will reject 54M
because fail for check (mask->control[band].legacy & basic_rates).
suppor rates of my AP:
Tag: Supported Rates 6(B), 9, 12(B), 18, 24(B), 36, 48, 54, [Mbit/sec]
Tag Number: Supported Rates (1)
Tag length: 8
Supported Rates: 6(B) (0x8c)
Supported Rates: 9 (0x12)
Supported Rates: 12(B) (0x98)
Supported Rates: 18 (0x24)
Supported Rates: 24(B) (0xb0)
Supported Rates: 36 (0x48)
Supported Rates: 48 (0x60)
Supported Rates: 54 (0x6c)
