[RFC PATCH v3 0/1] Bluetooth: btusb: UB500 reported maximum data length

From: Kyle Pepper

Hi Luiz,

LE Read Maximum Data Length reports TX/RX251, while LE Read Buffer
Size reports 27/eight. A separate raw HCI test verified sixteen
251-byte packets received byte-for-byte intact and completed, with
one packet outstanding at a time.

RFC v3 replaces 167 with the reported maximum TX length, retaining
eight LE credits. This establishes HCI251 acceptance, not physical
pool capacity or an absolute HCI limit. Audio with the revised
callback remains untested.

Prepared with LLM assistance.

Kyle
