Hi guys


In a forwarding [or RPS/RFS] setup, why should we populate cpu caches
with full frames content ? We only need first cache line to perform
routing [or RPS/RFS] decision.

-> DCA should be a knob (ethtool ?) that an admin can switch off and on,
port by port, not a CONFIG_IXGBE_DCA thing.

Thanks
