XP Cluster Global First Error Pointer
This field points to which of the 3 errors indicated in the XPGLBERRSTS register
happened first. This field is only valid when the corresponding status bit is set and
this field is rearmed to load again when the status bit indicated to by this pointer
is cleared by software from 1 to 0.Value of 0h corresponds to bit 0 in
XPGLBERRSTS register, value of 1h corresponds to bit 1, and so forth.

Lane Error Status
A value of 1b in any bit indicates if the corresponding PCIe Express Lane detected
lane based error.
