Subject: [PATCH v2 8/8] net: use new capable_or functionality
Date:   Mon,  2 May 2022 18:00:29 +0200
Message-Id: <20220502160030.131168-7-cgzones@googlemail.com>
In-Reply-To: <20220502160030.131168-1-cgzones@googlemail.com>
References: <20220217145003.78982-2-cgzones@googlemail.com>

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Precedence: bulk

Use the new added capable_or function in appropriate cases, where a task
is required to have any of two capabilities.

Reorder CAP_SYS_ADMIN last.
