Revert r330897:
This was intended to be a non-functional change. It wasn't. The commit message was thus wrong. In addition it broke arm, and merged crypto related code.
Revert with prejudice.
This revert skips files touched in r316370 since that commit was since MFCed. This revert also skips files that require $FreeBSD$ property changes.
Thank you to those who helped me get out of this mess including but not limited to gonzo, kevans, rgrimes.

o Don't access VPD even if hardware advertised the capability. It seems that some revision of controller hang while accessing the VPD. Because VPD access routine are unused, nuke it. o Let TWSI reload EEPROM if VPD capability is detected. Reloading EEPROM will also set ethernet address so age(4) now reads AGE_PAR0 and AGE_PAR1 register to get ethernet address. This removes a lot of hack and enhance readability a lot. o Double PHY reset timeout as it takes more time to take PHY out of power-saving state. o Explicitly check power-saving state by checking undocumented PHY registers. If link is not up, poke undocumented registers to take PHY out of power-saving state. This is the same way what Linux does. On resume, make sure to wake up PHY. o Don't rely on auto-clearing feature of master reset bit, just wait 1ms and check idle status of MAC. o Add PCI device revision information in bootverbose mode. This should fix occasional controller hang in device attach phase.

Add age(4), a driver for Attansic/Atheros L1 gigabit ethernet controller. L1 has several threshold/timer registers and they seem to require careful tuned parameters to get best performance. Datasheet for L1 is not available to open source driver writers so age(4) focus on stability and correctness of basic Tx/Rx operation. ATM the performance of age(4) is far from optimal which in turn means there are mis-programmed registers or incorrectly configured registers. Currently age(4) supports all known hardware assistance including - MSI support. - TCP Segmentation Offload. - Hardware VLAN tag insertion/stripping. - TCP/UDP checksum offload. - Interrupt moderation. - Hardware statistics counter support. - Jumbo frame support. - WOL support.
L1 gigabit ethernet controller is mainly found on ASUS motherboards. Note, it seems that there are other variants of hardware as known as L2(Fast ethernet) and newer gigabit ethernet (AR81xx) from Atheros. These are not supported by age(4) and requires a seperate driver. Big thanks to all people who reported feedback or tested patches.
