Subject: [PATCH 5.13 082/104] net/mlx5e: Fix page allocation failure for ptp-RQ over SF

From: Aya Levin <ayal@...dia.com>

[ Upstream commit 678b1ae1af4aef488fcc42baa663e737b9a531ba ]

Set the correct pci-device pointer to the ptp-RQ. This allows access to
dma_mask and avoids allocation request with wrong pci-device.
