2024-11-14r8169: copy vendor driver 2.5G/5G EEE advertisement constraintsHeiner Kallweit
Vendor driver r8125 doesn't advertise 2.5G EEE on RTL8125A, and r8126 doesn't advertise 5G EEE. Likely there are compatibility issues, therefore do the same in r8169. With this change we don't have to disable 2.5G EEE advertisement in rtl8125a_config_eee_phy() any longer. We use new phylib accessor phy_set_eee_broken() to mark the respective EEE modes as broken.

2024-10-23r8169: avoid unsolicited interruptsHeiner Kallweit
It was reported that after resume from suspend a PCI error is logged and connectivity is broken. Error message is: PCI error (cmd = 0x0407, status_errs = 0x0000) The message seems to be a red herring as none of the error bits is set, and the PCI command register value also is normal. Exception handling for a PCI error includes a chip reset what apparently brakes connectivity here. The interrupt status bit triggering the PCI error handling isn't actually used on PCIe chip versions, so it's not clear why this bit is set by the chip. Fix this by ignoring this bit on PCIe chip versions.

Register a6d/12 is shadowing register MDIO_AN_EEE_ADV2. So this line disables advertisement of EEE at 2.5G. Latest vendor driver r8125 doesn't do this (any longer?), so this mode seems to be safe.

There's not really a benefit here in taking the RTNL lock. The task handler does exception handling only, so we're in trouble anyway when we come here, and there's no need to protect against e.g. a parallel ethtool call. A benefit of removing the RTNL lock here is that we now can synchronously cancel the workqueue from a context holding the RTNL mutex.

2024-09-02r8169: add support for RTL8126A rev.bChunHao Lin
Add support for RTL8126A rev.b. Its XID is 0x64a. It is basically based on the one with XID 0x649, but with different firmware file.

2024-07-31r8169: don't increment tx_dropped in case of NETDEV_TX_BUSYHeiner Kallweit
The skb isn't consumed in case of NETDEV_TX_BUSY, therefore don't increment the tx_dropped counter.

net_dev->ethtool is a pointer to new struct ethtool_netdev_state, which currently contains only the wol_enabled field.

2024-05-28r8169: remove detection of chip version 11 (early RTL8168b)Heiner Kallweit
This early RTL8168b version was the first PCIe chip version, and it's quite quirky. Last sign of life is from more than 15 yrs ago. Let's remove detection of this chip version, we'll see whether anybody complains. If not, support for this chip version can be removed a few kernel versions later.

2024-05-28r8169: disable interrupt source RxOverflowHeiner Kallweit
Vendor driver calls this bit RxDescUnavail. All we do in the interrupt handler in this case is scheduling NAPI. If we should be out of RX descriptors, then NAPI is scheduled anyway. Therefore remove this interrupt source. Tested on RTL8168h.
