Message-Id: <cecdecdbe81c9ca86127413c6559be2d3ffcabd3.1488376601.git.dcaratti@redhat.com>

Subject: [PATCH] mka: Pass full structures down to macsec drivers' receive SA
ops
Clean up the driver interface by passing pointers to struct receive_sa
down the stack to the {create,enable,disable}_receive_sa() ops, instead
of passing the individual properties of the SA.
