MYNEWT-486: Controller cannot accept ACL data packets > 255 bytes.
> ACL data packet sizes of 256 or greater will not work.

> Project: Mynewt

> Components: Nimble
> Affects Versions: v1_0_0_beta1

> It appears that there is a bug in the controller. If the ACL data packet
> length is set to greater than 255, the controller will probably fail to send
> the packet. The issue is that the controller uses a uint8_t internally at
> some point and is truncating the packet length.
> There is a work-around for now: setting the BLE_LL_ACL_PKT_SIZE syscfg value
> to 255 or less. This can be done in a target or APP if desired. We will do
> some more testing on this to verify that this is an issue and that the
> work-around is functional. The code will also be fixed in the beta 1 release.
