net: thunderbolt: Fix the parameter passing of tb_xdomain_enable_paths()/tb_xdomain_disable_paths()

2025-08-20T16:30:34+00:00

[ Upstream commit 8ec31cb17cd355cea25cdb8496d9b3fbf1321647 ] According to the description of tb_xdomain_enable_paths(), the third parameter represents the transmit ring and the fifth parameter represents the receive ring. tb_xdomain_disable_paths() is the same case. [Jakub] Mika says: it works now because both rings ->hop is the same Acked-by: Mika Westerberg Link: https://lore.kernel.org/20250625051149.GD2824380@black.fi.intel.com Signed-off-by: zhangjianrong Link: https://patch.msgid.link/20250628094920.656658-1-zhangjianrong5@huawei.com Signed-off-by: Jakub Kicinski Signed-off-by: Sasha Levin

net: thunderbolt: Enable end-to-end flow control also in transmit

2025-08-20T16:30:34+00:00

[ Upstream commit a8065af3346ebd7c76ebc113451fb3ba94cf7769 ] According to USB4 specification, if E2E flow control is disabled for the Transmit Descriptor Ring, the Host Interface Adapter Layer shall not require any credits to be available before transmitting a Tunneled Packet from this Transmit Descriptor Ring, so e2e flow control should be enabled in both directions.

net: thunderbolt: Fix TCPv6 GSO checksum calculation

2023-09-15T12:45:05+00:00

Alex reported that running ssh over IPv6 does not work with Thunderbolt/USB4 networking driver. The reason for that is that driver should call skb_is_gso() before calling skb_is_gso_v6(), and it should not return false after calculates the checksum successfully. This probably was a copy paste error from the original driver where it was done properly.

We will be adding tracepoints to the driver so instead of littering the main network driver directory, move the driver into its own directory. While there, rename the module to thunderbolt_net (with underscore) to match with the thunderbolt_dma_test convention.
