 I'm glad to hear that the patch works correctly for such a 'mega' serial 
 card.
 
 
 I would still like to implement MSI-X interrupt handling. With standard 
 IRQs, I found that the jitter is too high on my OXPCIe954 based card for 
 pulse per second to work optimally with NTP, though it is usable.
 
 The most important thing is that this driver works 'as is' for a range 
 of cards on several FreeBSD versions. I hope it will be committed so 
 that others can use these excellent PCIe serial chips without patching 
 their kernels.
 
 
 I did my best to try to interest some committers, though without 
 success. The PR is on linimon's list of easy PRs

 I keep hoping that someone will commit this and close a PR that has been 
 open for 21 months. If you want to try some advocacy amongst committers, 
 be my guest!
 
 
 
 With best wishes,
 
 
 
 
 David
