Re: [RFC] Bluetooth: HCI H5 fast retransmit

Hi Marcel,

This patch is not so much out-of-scope of the H5 because specification
only gives "recommended parameters" regarding timeout calculation.

I tested it with only one H5 controller (rtl8723).
This mechanism is very beneficial with this controller due to a
relative high packet loss.

However I'm going to rework this patch to be more specific (only fast
retransmit if the invalid ack number is a duplicate of the last acked packet)
+ comments.

I don't see any obvious H5 incompatibility issue, therefore, extra flag
shouldn't be required.

Regards,
Loic
