The current extended ethernet statistics fetching involve doing several string operations, which causes performance issues if there are lots of statistics and/or network interfaces. This patchset changes the API for xstats to use integer identifiers instead of strings and implements this new API for the ixgbe, i40e, e1000, fm10k, and virtio drivers.
