Doesn't this byte array covert (and then write) to the same cpu endianess? __le32 mu = (__le32 *)info->mu_group.membership write(..., le32_to_cpu(mu)); I know something like above change is safe, but just checking...

The Group ID Management frame is an Action frame of category VHT. It is transmitted by the AP to assign or change the user position of a STA for one or more group IDs. Also, sniffer can use a given group id to monitor STA that belongs to that group. Notify underlying driver of changes via BSS_CHANGED_MU_GROUPS.
