Subject: [PATCH v6 1/4] net:ipv6:Add void *data to ndisc_send_na function
Date: Wed, 23 Mar 2022 08:09:03 -0400	[thread overview]
Message-ID: <20220323120906.42692-2-sunshouxin@chinatelecom.cn> (raw)
In-Reply-To: <20220323120906.42692-1-sunshouxin@chinatelecom.cn>

Adds void *data to ndisc_send_na stub function and
ndisc_send_na direct function. Update all places that
use both ndisc_send_na to pass NULL as the data parameter.
