gve: Remove the code of clearing PBA bit

2023-05-24T16:29:59Z

[ Upstream commit f4c2e67c1773d2a2632381ee30e9139c1e744c16 ] Clearing the PBA bit from the driver is race prone and it may lead to dropped interrupt events. This could potentially lead to the traffic being completely halted.

gve: Secure enough bytes in the first TX desc for all TCP pkts

2023-04-05T01:58:12Z

Non-GSO TCP packets whose SKBs' linear portion did not include the entire TCP header were not populating the first Tx descriptor with as many bytes as the vNIC expected. This change ensures that all TCP packets populate the first descriptor with the correct number of bytes.

gve: Cache link_speed value from device

2023-03-23T05:03:21Z

The link speed is never changed for the uptime of a VM, and the current implementation sends an admin queue command for each call. Admin queue command invocations have nontrivial overhead (e.g., VM exits), which can be disruptive to users if triggered frequently. Our telemetry data shows that there are VMs that make frequent calls to this admin queue command. Caching the result of the original admin queue command would eliminate the need to send multiple admin queue commands on subsequent calls to retrieve link speed.

gve: Reduce alloc and copy costs in the GQ rx path

2022-11-02T11:52:51Z

Previously, even if just one of the many fragments of a 9k packet required a copy, we'd copy the whole packet into a freshly-allocated 9k-sized linear SKB, and this led to performance issues. By having a pool of pages to copy into, each fragment can be independently handled, leading to a reduced incidence of allocation and copy. Signed-off-by: Shailend Chand Signed-off-by: David S.

net: drop the weight argument from netif_napi_add

2022-09-29T01:57:14Z

We tell driver developers to always pass NAPI_POLL_WEIGHT as the weight to netif_napi_add(). This may be confusing to newcomers, drop the weight argument, those who really need to tweak the weight can use netif_napi_add_weight().
