[dpdk-dev] [PATCH v2 09/26] net/qede/base: improve Tx-switching performance

In order to improve Tx switching performance an additional HSI parameter
called same-as-last-id is introduced. This resource allows FW caching the
txqs packet properties. Driver needs to set same-as-last-id to be equal to
the qzone.
