| Subject: [PATCH] macsec_linux: Hardware offload requires Linux headers >= v5.7 |
| |
| Hardware offload in Linux macsec driver is enabled in compile time if |
| libnl version is >= v3.6. This is not sufficient for successful build |
| since enum 'macsec_offload' has been added to Linux header if_link.h |
| in kernels v5.6 and v5.7, see commits: |
| - https://github.com/torvalds/linux/commit/21114b7feec29e4425a3ac48a037569c016a46c8 |
| - https://github.com/torvalds/linux/commit/76564261a7db80c5f5c624e0122a28787f266bdf |
| |
| New libnl with older Linux headers is a valid combination. This is how |
| hostapd build failure has been detected by Buildroot autobuilder, see: |
| - http://autobuild.buildroot.net/results/b59d5bc5bd17683a3a1e3577c40c802e81911f84/ |
| |
| Extend compile time condition for the enablement of the macsec hardware |
| offload adding Linux headers version check. |
| |
