Subject[PATCH 4.19 13/89] net: macsec: update SCI upon MAC address change.
Date
From: Dmitry Bogdanov <dbogdanov@marvell.com>

[ Upstream commit 6fc498bc82929ee23aa2f35a828c6178dfd3f823 ]

SCI should be updated, because it contains MAC in its first 6 octets.

Fixes: c09440f7dcb3 ("macsec: introduce IEEE 802.1AE driver")
