docs: networking: can: change bcm_msg_head frames member to support flexible array

2025-09-19T14:35:49+00:00

[ Upstream commit 641427d5bf90af0625081bf27555418b101274cd ] The documentation of the 'bcm_msg_head' struct does not match how it is defined in 'bcm.h'. Changed the frames member to a flexible array, matching the definition in the header file.

mptcp: disable add_addr retransmission when timeout is 0

2025-08-28T14:31:07+00:00

commit f5ce0714623cffd00bf2a83e890d09c609b7f50a upstream. When add_addr_timeout was set to 0, this caused the ADD_ADDR to be retransmitted immediately, which looks like a buggy behaviour. Instead, interpret 0 as "no retransmissions needed". The documentation is updated to explicitly state that setting the timeout to 0 disables retransmission.

Documentation: networking: Add a caveat to nexthop_compat_mode sysctl

2024-12-19T17:13:16+00:00

[ Upstream commit bbe4b41259a3e255a16d795486d331c1670b4e75 ] net.ipv4.nexthop_compat_mode was added when nexthop objects were added to provide the view of nexthop objects through the usual lens of the route UAPI. As nexthop objects evolved, the information provided through this lens became incomplete. For example, details of resilient nexthop groups are obviously omitted. Now that 16-bit nexthop group weights are a thing, the 8-bit UAPI cannot convey the >8-bit weight accurately. Instead of inventing workarounds for an obsolete interface, just document the expectations of inaccuracy.
