[dpdk-dev] [PATCH 07/26] ixgbe/base: provide unlocked I2C methods
Wenzhuo Lu

Fri Jun 5 07:21:39 CEST 2015
Most I2C accesses take and release semaphores for each access. It's
also necessary to perform multiple I2C operations under the same
holding of the semaphore, so provide unlocked I2C methods for that
purpose.
