From: Jacob Keller Date: Mon, 6 Feb 2017 22:38:39 +0000 (-0800) Subject: i40e: don't use arrays for (src|dst)_ip X-Git-Tag: MMI-PSA29.97-13-9~5649^3~414^2~9 X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=8ce43dce6f272202dcd127e0e288b37277ca87dd;p=GitHub%2FMotorolaMobilityLLC%2Fkernel-slsi.git i40e: don't use arrays for (src|dst)_ip The code originally included src_ip and dst_ip with enough space to support ipv6 filters. However, no actual support for ipv6 filters has been implemented. Thus, remove the arrays and just use __be32 values. Should ipv6 support be added in the future, we can replace these with a union that has sizes for both values.
