Previous message: [dpdk-dev] [PATCH 00/21] update ixgbe base code
Next message: [dpdk-dev] [PATCH v2 0/3] add RSS support for IPv6 prefix
Messages sorted by: [ date ] [ thread ] [ subject ] [ author ]
RSS for IPv6 prefix fields are supported in this patch, so that we
can use prefixes instead of full IPv6 address for RSS. These prefixes
include the first 32, 48, 64 bits of both SRC and DST IPv6 address.
