MTSDU[15:0]:
MTSDU[15:0] represents the user programmable maximum length of the transmit
CPAAL5 Service Protocol Unit (SDU) in bytes. If the PCI Host presents a
CPAAL5_SDU that exceeds the maximum, the LASAR-155 will indicate an error
via an interrupt bit and return the CPAAL5_SDU to the PCI Host on the Transmit
Descriptor Reference Free Queue immediately.
