The bisect is complete and yields this result

     ice: don't busy wait for Rx queue disable in ice_qp_dis()

     [ Upstream commit 1ff72a2f67791cd4ddad19ed830445f57b30e992 ]

     When ice driver is spammed with multiple xdpsock instances and flow
     control is enabled, there are cases when Rx queue gets stuck and unable
     to reflect the disable state in QRX_CTRL register. Similar issue has
     previously been addressed in commit 13a6233b033f ("ice: Add support to
     enable/disable all Rx queues before waiting").

     To workaround this, let us simply not wait for a disabled state as 
later
     patch will make sure that regardless of the encountered error in the
     process of disabling a queue pair, the Rx queue will be enabled.

     Fixes: 2d4238f55697 ("ice: Add support for AF_XDP")
