[PATCH net 0/2] net: mana: Fix debugfs directory naming and file lifecycle

From: Erni Sri Satya Vennela

Date: Wed Apr 08 2026 - 04:13:11 EST


This series fixes two pre-existing debugfs issues in the MANA driver.

Patch 1 fixes the per-device debugfs directory naming to use the unique
PCI BDF address via pci_name(), avoiding a potential NULL pointer
dereference when pdev->slot is NULL (e.g. VFIO passthrough, nested KVM)
and preventing name collisions across multiple PFs or VFs.

Patch 2 moves the current_speed debugfs file creation from
mana_probe_port() to mana_init_port() so it survives detach/attach
cycles triggered by MTU changes or XDP program changes.

Erni Sri Satya Vennela (2):
net: mana: Use pci_name() for debugfs directory naming
net: mana: Move current_speed debugfs file to mana_init_port()
