The referenced fix is incomplete. It correctly computes
bond_dev->gso_partial_features across slaves, but unfortunately
netdev_fix_features discards gso_partial_features from the feature set
if NETIF_F_GSO_PARTIAL isn't set in bond_dev->features.
This is visible with ethtool -k bond0 | grep esp:
tx-esp-segmentation: off [requested on]
esp-hw-offload: on
esp-tx-csum-hw-offload: on
This patch reworks the bonding GSO offload support by:
- making aggregating gso_partial_features across slaves similar to the
other feature sets (this part is a no-op).
- advertising the default partial gso features on empty bond devs, same
as with other feature sets (also a no-op).
- adding NETIF_F_GSO_PARTIAL to hw_enc_features filtered across slaves.
- adding NETIF_F_GSO_PARTIAL to features in bond_setup()
With all of these, 'ethtool -k bond0 | grep esp' now reports:
tx-esp-segmentation: on
esp-hw-offload: on
esp-tx-csum-hw-offload: on

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
