#11 Add ERC (Error Recovery Control) support to hdparm

[Greg]

ATA-8 in the TSC section has added ERC support.

It allows the drive internal retry logic to be controlled. Many raid configurations like to have fail fast drives, so setting the ERC to small timeout is encouraged for mdraid usage (I believe).

Drives are shipping that support this feature.

WD was the first and they called it TLER. That was before the ATA-8 spec. had added ERC support.

I'm not sure if ERC and TLER are the same from a sata abi perspective or not.

smartctl already has support, but this seems like a natural for hdparm as well.
