Changes to support TX NAPI in the axienet driver, as well as fixing
a potential concurrency issue in the TX ring pointer handling.
Supersedes v5 of the individual patch
"net: axienet: Use NAPI for TX completion path".
Changed since v5: Replaced spinlock with fixes to the way the TX ring
tail pointer is updated, and broke those changes into a separate patch.
Changed since v4: Added locking to protect TX ring tail pointer against
concurrent access by TX transmit and TX poll paths.
Changed since v3: Fixed references to renamed function in comments
Changed since v2: Use separate TX and RX NAPI poll handlers to keep
completion handling on same CPU as TX/RX IRQ. Added hard/soft IRQ
benchmark information to commit message.
Changed since v1: Added benchmark information to commit message, no
code changes.
