From: Soontak Lee <soontak.lee@xxxxxxxxxxx>
When plumbing rxiv for (GTK) keys, current code does not use seq/seq_len
when present nor set iv_initialized for iovar wsec_key. This could
result in missing broadcast traffic after GTK rekey. The fix is setting
iv_initialized and using seq/seq_len for iovar wsec_key.
