Sad :(
The introduced anonymous structure gets aligned on the minimum cache
line size (64 bytes): with this change, ctx[] move from offset 256, to
offset 192.
Similarly, nodes[] moves from offset 320 to offset 256.
As we discussed offlist, there are a few options to workaround this
issue (like moving nodes[] inside the anonymous struct though it still
results in an increased rte_node struct, or like adding an explicit
padding field right before the newly introduced anonymous struct,
...).
[snip]
For those two reasons, it is better to revisit this patch and have it
ready for the next release.
While at it, it may be worth cleaning up the rte_node structure in
v24.11, if so, please announce in a deprecation notice for this
planned ABI breakage.
Jerin, wouldn't it be better if we managed to fill in that 64 bytes
hole?
I don't know what to announce precisely about the breakage nature.
