In port info command output, 'show port info all', supported RSS offload
types printed one type per line, and although this information is not
most important part of the command it takes big part of the command
output.
In port RSS hash and flow RSS command output, 'show port 0 rss-hash',
and 'flow query 0 0 rss', all enabled RSS types are printed on one line.
If there are many types, the print will be very long.
Compacting these RSS offloads and types output by fixing the length
of the
character string printed on each line, instead of one per line or one
line.
Output becomes as following:
Supported RSS offload flow types:
ipv4-frag ipv4-tcp ipv4-udp ipv4-sctp ipv4-other ipv6-frag
ipv6-tcp
ipv6-udp ipv6-sctp ipv6-other l4-dst-only l4-src-only l3-dst-only
l3-src-only

If you go with 'rss_type_table[]', above function can be used for both
'port_infos_display()' and 'rss_types_display()', what do you think?
I just don't think it's appropriate to use this table for that.
I put some more comment to other patch on why 'rss_type_table[]' can be
used.
And perhaps 'rss_offload_types_display()' can get length as parameter.
Ack.
