https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D254695 --- Comment #35 from Michael Tuexen <tuexen@freebsd.org> --- We need something along the lines of your proposed fix. However, the number= of entries/exist of the epoch should be kept minimal. So we might want to have= the author of the driver to have a look. But first we need to get the contracts of the TCP LRO code nailed down. Especially in the case when the HPTS is used. Let me come up with a patch f= or that first to get the contract fixed. Then we can propose a functional, may= be performance wise not optimal fix for the MS specific drive. Hopefully some people with expertise on the drive can help out. --=20 You are receiving this mail because: You are on the CC list for the bug.=
