igb: Fix missing time sync events

2024-03-06T17:20:23+00:00

Fix "double" clearing of interrupts, which can cause external events or timestamps to be missed. The E1000_TSIRC Time Sync Interrupt Cause register can be cleared in two ways, by either reading it or by writing '1' into the specific cause bit. This is documented in section 8.16.1. The following flow was used: 1. read E1000_TSIRC into 'tsicr'; 2. handle the interrupts present into 'tsirc' and mark them in 'ack'; 3. write 'ack' into E1000_TSICR; As both (1) and (3) will clear the interrupt cause, if the same interrupt happens again between (1) and (3) it will be ignored, causing events to be missed. Remove the extra clear in (3).

intel: make module parameters readable in sys filesystem

2024-03-05T04:49:58+00:00

Linux users sometimes need an easy way to check current values of module parameters. For example the module may be manually reloaded with different parameters. Make these visible and readable in the /sys filesystem to allow that. But don't make the "debug" module parameter visible as debugging is enabled via ethtool msglvl.

net: adopt skb_network_offset() and similar helpers

2024-03-04T08:47:06+00:00

This is a cleanup patch, making code a bit more concise. 1) Use skb_network_offset(skb) in place of (skb_network_header(skb) - skb->data) 2) Use -skb_network_offset(skb) in place of (skb->data - skb_network_header(skb)) 3) Use skb_transport_offset(skb) in place of (skb_transport_header(skb) - skb->data) 4) Use skb_inner_transport_offset(skb) in place of (skb_inner_transport_header(skb) - skb->data) Signed-off-by: Eric Dumazet Acked-by: Edward Cree # for sfc Signed-off-by: David S.

igb: extend PTP timestamp adjustments to i211

2024-02-29T04:16:48+00:00

The i211 requires the same PTP timestamp adjustments as the i210, according to its datasheet. To ensure consistent timestamping across different platforms, this change extends the existing adjustments to include the i211. The adjustment result are tested and comparable for i210 and i211 based systems.
