From: Stijn Tintel Date: Tue, 3 Jan 2017 23:15:23 +0000 (+0100) Subject: x86/64: enable AES-NI support in kernel X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=301301da2b2998177d4c34521f933c828972a985;p=openwrt%2Fstaging%2Fblogic.git x86/64: enable AES-NI support in kernel The kernel will detect if the host supports this, so we can just enable it in the kernel config. Tested on an APU2 with AES-NI support and a KVM VM on a Xeon E5520 host without AES-NI support. Throughput over an IPsec tunnel between these 2 hosts increased from ~63Mbps to ~140Mbps. Ciphers: AES_GCM_16_256/PRF_HMAC_SHA2_512/ECP_521.
