Claim:
1. A method comprising: receiving, from a local counter, a first counter value, the first counter value representing a position of a first stream of deskewed data on a first multi-lane link compliant with a peripheral component interface express (PCIe) protocol; receiving, from a communications interface associated with a second stream of deskewed data, a second counter value, the second counter value representing a position of the second stream of deskewed data on a second multi-lane link compliant with a peripheral component interface express (PCIe) protocol; obtaining a data portion of the first counter value based on a lookup of an address portion of the first counter value using an address portion of the second counter value; comparing the data portion of the first counter value with a data portion of the second counter value; and stalling the first stream of deskewed data from transmission on a multi-lane PCIe link when the data portion of the first counter value is less than the data portion of the second counter value.
