ixl(4): Fix hardmtu and rxmax
Table 1-3. Link layer Ethernet port features
Maximum Transmit Unit Size (MTU) is 9728 - Ethernet header/CRC =
9728 - 18 = 9710 bytes (jumbo frames)
MTU can be further reduced by additional header fields such as
Virtual Local Area Network (VLAN) tag(s), etc.
Table 8-12. LAN Rx Queue Context in the Private Host Memory
The "rxmax" parameter defines the whole packet size starting at
the L2 header up to including the Ethernet CRC.
...
The RXMAX must not be set to a larger value than 5 x DBUFF
(since receive packet must never span on more than 5 buffers).
