Card not detected

[eddie4]

Hello,

I have been trying for a few days to get moongen to work. But i keep running into issues. It seems like this should work from where i am standing. I have attempted both ubuntu 16.04 and 18.04 but i keep running into issues that the card is detected in DPDK but not detected in moongen.

card looks to be supported it's an BCM57800

root@kvm344:~/MoonGen# python libmoon/deps/dpdk/usertools/dpdk-devbind.py -s

moongen output. Note it does have 2MB hugepages just not 1GB ones

Any advice you can give would be appreciated.

ps. The required packages in the howto are missing: Python dpdk and libtbb-dev

it's disabled by default in DPDK; compile DPDK with CONFIG_RTE_LIBRTE_BNX2X_PMD=n

Thanks for the quick response.

I have purged the apt version of dpdk from the system

I have build DPDK that is included in libmoon with CONFIG_RTE_LIBRTE_BNX2X_PMD=y and during the compile i see it getting included however I still have the same issue with the same output as above.

Bought an Intel x520 works instantly. You can resolve this issue.
