  TITLE:=xdp-filter - a simple XDP-powered packet filter
endef

define Package/xdp-filter/description
xdp-filter is a packet filtering utility powered by XDP. It is deliberately
simple and so does not have the same matching capabilities as, e.g.,
netfilter. Instead, thanks to XDP, it can achieve very high drop rates:
tens of millions of packets per second on a single CPU core.

endef

define Package/xdp-loader/description
xdp-loader is a simple loader for XDP programs with support for attaching
multiple programs to the same interface. To achieve this it exposes the same
load and unload semantics exposed by the libxdp library.
