Are there any plans to enable PCIE Advanced Error handling (AER) in any of the Intel NIC drivers? The Linux kernel has support for AER, see drivers/pci/pcie/aer. When a PCIE error is reported to the PCIE root port the do_recovery function is invoked through the root port's AER interrupt handler. This function invokes the callbacks defined in struct pci_error_handlers within a driver for recovery. The Intel NICs (e1000, e1000e, igb, igxbe) already implement these callbacks, so they may only a small step away from supporting AER. I would like to know what the current position toward enabling AER in these drivers is. Are there any objections or known obstacles? Are patches welcome?
