X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=197b672c40613a53a78a568a1957f2c23c343c1f;p=openwrt%2Fstaging%2Flinusw.git

kernel: crypto: add kmod-crypto-chacha20poly1305

Needed by strongSwan IPsec VPN for strongswan-mod-chapoly. Not to be confused with
kmod-crypto-LIB-chacha20poly1305, which is an 8-byte nonce version used
by wireguard.
