Hi:
I am attempting to use DPDK v2.1.0 and noticed that there appears to be
nascent support for jumbo packets. For example, in the example
application l2fwd, the comments reference an EAL parameter
--enable-jumbo. However, in the EAL library routines, that parameter
doesn't exist. I looked into the librte_ether/rte_ethdev.c routine and
found that if I modify the l2fwd example as so:
modify Line 119:
.jumbo_frame = 0
to
.jumbo_frame = 1,
.max_rx_pkt_len = 9000,
that the program will compile and run, but any packets larger than 2006
bytes are truncated. What do I need to do in order to make the program
support jumbo packets (9000 bytes in my case)? Or is there a different
but better way to support 9000 byte packets at rates close to 10 Gb/s?
Thanks,
Lawrence
