/* New Flags definition in Receive Direction
Bit 0 - Bundle trailer needs 1 extra block towards the end
If this bit is set, it implies that the last msg of the bundle has a
lookahead trailer and it needs additional block.
This bit is set in the 1st pack of the bundle.
It gives the host a heads up on the size it wants to receive.
HOST calculates the total bundle length (for CMD53) as
L = n * [padded length] + size of trailer information
n: number of msgs in the bundle
padded length: padded length of 1st msg of the bundle.
Bit 1- Recv Trailer is present, length of data is in control byte 0
This is contained in the last packet of the bundle
Bits 2-7 indicate the Bundle count. When non-zero the number of frames
behind the current frame with the same padded length. The split is :
Bit 2..3 Higher 2 bits of Recv Bundle Count
Bit 4..7 Lower 4 bits of Recv Bundle Count
(This weird arrangement is to stick to legacy implementation where
only bits 4..7 were used)
