According to this [commit](https://git.kernel.org/pub/scm/network/wireless/iwd.git/commit/?id=1db8a85a60c64523) iwd no longer needs ARC4 support in the kernel. It also looks like the tags for 1.9 and 1.10 also include this commit. In recent kernels CONFIG_CRYPTO_ARC4 is marked as obsoleted with this [commit](https://patchwork.kernel.org/project/linux-nfs/patch/20200831151649.21969-8-ardb@kernel.org/#23607537). The latter commit also states that iwd doesn't need it anymore. Reproducible: Always Steps to Reproduce: 1. Build a 5.10 kernel with CRYPTO_USER_API_ENABLE_OBSOLETE disabled. 2. The above will automatically disable CONFIG_CRYPTO_ARC4 3. Try to build iwd-1.11, it will fail with error that CONFIG_CRYPTO_ARC4 is not enabled. Actual Results: Iwd build fails. Expected Results: According to the referenced commits this configuration option should not be needed and the iwd build should succeed. I can provide a patch if requested.

Thanks for reporting the unneeded ARC4 option, I will remove it. But, this shouldn't make your build fail. All of the config checks are non-fatal here (CONFIG_CHECK="~CRYPTO_ARC4" instead of CONFIG_CHECK="CRYPTO_ARC4").

All of the config checks are > non-fatal here (CONFIG_CHECK="~CRYPTO_ARC4" instead of > CONFIG_CHECK="CRYPTO_ARC4"). You are correct - it actually failed due to ell-0.35 dependency, which I saw that it is already fixed. I misread the output from emerge. Thanks a lot for the prompt reaction!
