Subject: [dpdk-dev] [PATCH] doc: deprecation notice for change of ether struct alignment
Date: Tue,  9 Jul 2019 15:58:36 +0100
Message-ID: <20190709145836.43493-1-bruce.richardson@intel.com> (raw)

The ethernet address structure alignment will be changed to 2B alignment in
19.11. Flag this to users.

Impact is expected to be minimal for this change since ethernet addresses
are generally 2B aligned anyway.

 Deprecation Notices
 -------------------
 
+* net: The alignment of the ethernet address structure in DPDK,
+  ``rte_ether_addr`` will be increased to two, i.e. 16-bit aligned, in the
+  19.11 release. This will only affect any data structures where an ethernet
+  address is currently aligned on a single byte boundary.
+
 * meson: The minimum supported version of meson for configuring and building
   DPDK will be increased to v0.47.1 (from 0.41) from DPDK 19.05 onwards. For
   those users with a version earlier than 0.47.1, an updated copy of meson
-- 
2.21.0
