Do some reorganization of transmit logic path:
   * move transmit queue full idle to separate routine
   * add a cpu_relax()
   * eliminate some of the uneeded goto's
   * if queue is still stopped, go back to main thread loop.
   * don't give up transmitting if quantum is exhausted (be greedy)

TX completions were running in a workqueue queued by the ISR.  This
patch moves the processing of TX completions to an existing RSS NAPI
context.
Now each irq vector runs NAPI for one RSS ring and one or more TX

Currently we downshift to MSI/Legacy if we don't get enough vectors for

Currently we have three types of RX rings.

1) Default ring - services rx_ring for broadcast/multicast, handles
firmware events, and errors.

2) TX completion ring - handles only outbound completions.

3) RSS ring - handles only inbound completions.

This patch gets rid of the default ring type and moves it's functionality
into the first RSS ring.  This makes better use of MSIX vectors since
they are a limited resource on some platforms.

bonding: Have bond_check_dev_link examine netif_running

	Some network devices do not call netif_carrier_off when they
are set administratively down.  Have the bonding link check function
also inspect the netif_running state.  Ignore netif_running if the
bond_check_dev_link function is called with "reporting" set, as in that
case it's inspecting the capabilities of the non-netif_carrier device
driver.

The `val' variable in ath5k_eeprom_read_turbo_modes() is used
uninitialized.  gcc 4.4.1 with -fno-inline-functions-called-once reports
it:

eeprom.c: In function 'ath5k_eeprom_read_turbo_modes':
eeprom.c:441: warning: 'val' may be used uninitialized in this function

Comparing the code to the Atheros HAL, it's clear that the split between
ath5k_eeprom_read_modes() and ath5k_eeprom_read_turbo_modes() was
incorrect.

The Atheros HAL reads both turbo and non-turbo data from EEPROM in one
function.  Some turbo mode parameters are derived from the same EEPROM
values as non-turbo parameters, just from different bits.

Merge ath5k_eeprom_read_turbo_modes() into ath5k_eeprom_read_modes() to
fix the warning.  The actual values and offsets have been cross-checked
against Atheros HAL.
