This patch migrates the ISR parameter from struct net_device to struct
tg3_napi. Checkpatch complains about the existence of the preexisting
IRQF_SAMPLE_RANDOM flag. I've opted to keep this patch conservative and
let it continue to exist until the flag gets officially purged from the
kernel.

On TI's DA850/OMAP-L138 EVM, MAC address is stored in SPI
flash which is accessed using MTD interface.
This patch delays the initialization of DaVinci EMAC driver
by changing module_init to late_initcall. This helps SPI and
MTD drivers to get initialized before EMAC thereby enabling
EMAC driver to read the MAC address while booting and use it.

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.

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.
