This patchset introduces three new features and critical fixes for our
recent release cycle.
Patches 1-2 add support for UDP Segmentation Offload (USO) to improve
large-packet transmission performance for UDP workloads.
Patch 3 enables VFs to sense PF ifconfig down/up events, allowing
better fault tolerance and fast recovery in virtualized environments.
Patch 4 adds the missing VF support for the Amber-Lite 40G NICs, which
was previously omitted in the initial integration.
---
v4:
- Patches 1-4: add release notes
- Patch 3: consume the mailbox message before checking the CTS flag;
separate CTS validation from link status processing by
returning early after handling a CTS-less control message;
make pf_running atomic.
---
v3:
- Patches 1-2: change from new feature to bug fix.
- Patch 3: fix link status update in txgbevf_get_pf_link_status();
extend speed mask from 0xFFF0 to 0x1FFFFE for 40G speed;
reduce msgbuf array to a single u32 variable;
correct commit message.
- Patch 4: add a cleanup note in commit message for dropping the
redundant mac type check in txgbevf_check_mac_link_vf();
remove a redundant blank line in txgbe_reset_hw_vf().
---
v2:
- Rebased on top of commit 72fdcb7bd19d to resolve conflict in
drivers/net/txgbe/base/txgbe_type.h.
- No code changes compared to v1.
