What's the RSS filter function?

问题

I'm looking some doc about RSS filter funciton. NIC is Intel I210 and driver is e1000. I found some functions about RSS filter. Like:

eth_igb_start => igb_filter_restore => igb_rss_filter_restore => igb_config_rss_filter

igb_config_rss_filter will write RSS configure(rss reta, rss key and rss protocol) to NIC register.

My question is what's the different between igb_config_rss_filter and igb_rss_configure? Can you share some doc about DPDK filter?

Thanks

igb_config_rss_filter is used by the flow filter function. For example, if you create a flow filter rule, this function will be invoked.

igb_rss_configure is used to config RSS function.
