net: amd-xgbe: disable interrupts during pci removal

2022-02-09T12:52:59+00:00

Hardware interrupts are enabled during the pci probe, however, they are not disabled during pci removal. Disable all hardware interrupts during pci removal to avoid any issues.

net: amd-xgbe: ensure to reset the tx_timer_active flag

Ensure to reset the tx_timer_active flag in xgbe_stop(), otherwise a port restart may result in tx timeout due to uncleared flag.

net: amd-xgbe: Fix skb data length underflow

2022-01-28T02:24:54+00:00

There will be BUG_ON() triggered in include/linux/skbuff.h leading to intermittent kernel panic, when the skb length underflow is detected. Fix this by dropping the packet if such length underflows are seen because of inconsistencies in the hardware descriptors.

net: amd-xgbe: Disable the CDR workaround path for Yellow Carp Devices

Yellow Carp Ethernet devices do not require Autonegotiation CDR workaround, hence disable the same. Co-developed-by: Shyam Sundar S K Signed-off-by: Shyam Sundar S K Signed-off-by: Raju Rangoju Signed-off-by: Jakub Kicinski

net: amd-xgbe: Alter the port speed bit range

2021-12-21T02:42:39+00:00

Newer generation Hardware uses the slightly different port speed bit widths, so alter the existing port speed bit range to extend support to the newer generation hardware while maintaining the backward compatibility with older generation hardware. The previously reserved bits are now being used which then requires the adjustment to the BIT values, e.g.: Before: PORT_PROPERTY_0[22:21] - Reserved PORT_PROPERTY_0[26:23] - Supported Speeds After: PORT_PROPERTY_0[21] - Reserved PORT_PROPERTY_0[26:22] - Supported Speeds To make this backwards compatible, the existing BIT definitions for the port speeds are incremented by one to maintain the original position.

net: amd-xgbe: Add Support for Yellow Carp Ethernet device

2021-12-21T02:42:39+00:00

Yellow Carp Ethernet devices use the existing PCI ID but the window settings for the indirect PCS access have been altered. Add the check for Yellow Carp Ethernet devices to use the new register values.

net_tstamp: add new flag HWTSTAMP_FLAG_BONDED_PHC_INDEX

2021-12-14T12:28:24+00:00

Since commit 94dd016ae538 ("bond: pass get_ts_info and SIOC[SG]HWTSTAMP ioctl to active device") the user could get bond active interface's PHC index directly. But when there is a failover, the bond active interface will change, thus the PHC index is also changed. This may break the user's program if they did not update the PHC timely. This patch adds a new hwtstamp_config flag HWTSTAMP_FLAG_BONDED_PHC_INDEX. When the user wants to get the bond active interface's PHC, they need to add this flag and be aware the PHC index may be changed. With the new flag. All flag checks in current drivers are removed. Only the checking in net_hwtstamp_validate() is kept. Suggested-by: Jakub Kicinski Signed-off-by: Hangbin Liu Signed-off-by: David S. Miller
