Tested this series with a forced transfer ring expansion and all worked well. I'll add this internally first and then later send it forward after the merge window. Thanks Mathias
Enlarge the XHCI Event Ring to cope with high load situations by allowing more than one segment. This second iteration seeks to address all of Mathias' review feedback on v1: * Patch [01/10]: Use ERST_DESI_MASK instead of ERST_PTR_MASK when constructing the new ERDP value to avoid carrying over a set EHB bit. * Patch [04/10]: Only use up to 2 Event Ring segments by default (instead of 8). * Patch [05/10]: New patch to adjust segment numbers after ring expansion. * Patch [08/10]: New patch to clean up ERST_PTR_MASK inversion. Several other issues caught my eye and I'm including fixes and cleanups for those as well.
