[dpdk-users] TESTPMD: show port <i> rss-hash usage

[Michael Sowka]

Hello folks, I'm a little thrown off by testpmd 'show port rss-hash'
command, specifically why does it accept the first argument (the rss_type).
Following the code down to rte_ethdev.c, and subsequently into the ixgbe
driver (i'm using an X520 card), it seems it reports back the same set of
rss hash function pulled from the cards registers (and rsk for that
matter), no matter what arguments to the show port command are provided...

Are these show port rss-hash arguments there to support some more advanced
NICs in some more elaborate form of rss, ? Could it be some inconsistency /
legacy code in testpmd, or is it really my lack of knowledge on rss
functionality, ?

Appreciate your insight, Mike
