Depending on the Bluetooth features enabled, the HCI packets can be 264 Bytes long. For HCI over USB the HCI packet is handled in data stage of USB transfer. Buffer for the data stage was too short and USB driver was STALLing the data stage making it unable to complete. Extend the data stage buffer to 266 Bytes if HCI USB is selected and BT_RX_BUF_LEN > 127 indicating that longer HCI packets are needed. Signed-off-by: Emil Obalski <emil.obalski@nordicsemi.no>

This option provides a dedicated work queue that is used for

|
all offloaded operations initiated by the USB subsystem.
|
|
This prevents deadlock situations where tasks on the system
|
|
workqueue inadvertently initiate operations that block, such
|
|
as UART transmission on CDC-ACM, preventing the system work
|
|
queue from making progress on the USB tasks that would
|
|
release the task.

Without this the system work queue is used for all USB
|
|
offloaded transfers.

be preempted by any other thread until finished.
