[ Upstream commit 80df4706357a5a06bbbc70273bf2611df1ceee04 ]
macsec_is_configured incorrectly uses secy->n_rx_sc to check if some RXSCs exist. secy->n_rx_sc only counts the number of active RXSCs, but there can also be inactive SCs as well, which may be stored in the driver (in case we're disabling offloading), or would have to be pushed to the device (in case we're trying to enable offloading).
As long as RXSCs active on creation and never turned off, the issue is not visible.
