Subject: [PATCH rtw-next v4 04/14] wifi: rtw89: Add rtw8851b_dle_mem_usb{2,3}
Date: Mon, 30 Jun 2025 23:42:24 +0300 [thread overview]
Message-ID: <91622304-614e-4e91-bf2f-7688cf44070b@gmail.com> (raw)
In-Reply-To: <7880bca2-17de-4d55-93a1-16977dd6502e@gmail.com>
Add rtw8851b_dle_mem_usb2 and rtw8851b_dle_mem_usb3 and their various
quotas and sizes in struct rtw89_mac_size_set.
"dle" could be "Data Link Engine" or "Double Link Engine". These are
some parameters needed for RTL8851BU.
