Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=...
--------------------------------
[ Upstream commit f5728a418945ba53e2fdf38a6e5c5a2670965e85 ]
Commit 6624e780a577fc596788 ("ice: split ice_vsi_setup into smaller functions") has refactored a bunch of code involved in PFR. In this process, TC queue number adjustment for XDP was lost. Bring it back.
Lack of such adjustment causes interface to go into no-carrier after a reset, if XDP program is attached, with the following message:
ice 0000:b1:00.0: Failed to set LAN Tx queue context, error: -22 ice 0000:b1:00.0 ens801f0np0: Failed to open VSI 0x0006 on switch 0x0001 ice 0000:b1:00.0: enable VSI failed, err -22, VSI index 0, type ICE_VSI_PF ice 0000:b1:00.0: PF VSI rebuild failed: -22 ice 0000:b1:00.0: Rebuild failed, unload and reload driver
