### Test FT Reassociation Request Frame Retransmission

Source: https://github.com/cgit/hostap/blob/main/tests/cipher-and-key-mgmt-testing.txt

Tests FT Reassociation Request frame retransmission on an AP device. This test requires a sniffer for analysis. It involves verifying unicast traffic, reissuing a reassociation request, and then verifying traffic again, looking for PN resets.

```bash
wpa_cli "raw RESEND_ASSOC"
```
