[PATCH 08/13] SME: Add support for handling association with MLD

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



In case that the AP supports MLD, request an MLD association
from the driver.

When processing the association event from the driver verify
that the multi link information in the association response ML
element matches the links on which the association was expected.
