Re: [dpdk-dev] Loading external PMD

[Eli Britstein <eli.britstein@toganetworks.com>]

Hi

In your PMD, you should mark your init function as constructor, in which you should register your PMD as a DPDK driver.
You can look at Intel's "memnic" example (though not maintained, and not being compiled with recent versions, you can take it as a reference).

The function I mean from it:

/* shared object initializer */
void __attribute__((constructor))
rte_memnic_pmd_init(void)
{
        rte_eth_driver_register(&rte_memnic_pmd);
}
