Subject: [PATCH v2 7/8] qmi: gprs-context: Parse IPv6 context settings
Date: Mon, 6 May 2024 16:58:01 -0500 [thread overview]
Message-ID: <20240506215804.57124-7-denkenz@gmail.com> (raw)
In-Reply-To: <20240506215804.57124-1-denkenz@gmail.com>
Similarly to get_settings_ipv4, add get_settings_ipv6 function which
will parse the relevant TLVs present when GET_SETTINGS response
indicates IPv6 family is in use.
