The first step toward using NAPI in the UD/TX flow is to separate between two flows, the NAPI and the xmit, meaning no use of shared variables between both flows. This patch takes out the tx_outstanding variable that was used in both flows and instead the driver uses the 2 cyclic ring variables: tx_head and tx_tail, tx_head used in the xmit flow and tx_tail in the NAPI flow.
