[dpdk-dev] [PATCH 13/18] ixgbe: semaphore mask move into hardware physical information

[Ouyang Changchun <changchun.ouyang@intel.com>]

This patch stores lan_id and physical semaphore mask into hardware physical information, 
and use them to control read and write physical registers in IXGBE base code.
