You are protected by the tx_lock spinlock, but this is fragile as you
could very well remove this spinloc
Initially, a NAPI TX routine has been implemented separately from
NAPI RX, as done on the freescale/gianfar driver.
By merging NAPI RX and NAPI TX, we reduce the amount of TX completion
interrupts.
Handling of the budget in association with TX interrupts is based on
