Burst-interleaved mode occurs when packets with different channel numbers are
burst interleaved on the Interlaken interface. In other words, one burst contains data
representing a portion of one packet, while the next burst contains data representing a
portion of another packet (from a different channel). In Burst-interleaved mode, the
size of bursts on the Interlaken interface is governed by the
tx_bctlin<N> input (see Use of tx_bctlin),
ctl_tx_burstshort, ctl_tx_burstmax, and the
changing of the channel number tx_chanin<N> as data from different
packets is interleaved.
