Subject: [PATCH rtw-next 1/6] wifi: rtlwifi: use struct ieee80211_pspoll for the PS Poll reserved page
Date: Tue, 10 Nov 2026 12:44:04 -0600	[thread overview]
Message-ID: <20261110184409.42205-2-rishik.yechuri.code@gmail.com> (raw)
In-Reply-To: <20261110184409.42205-1-rishik.yechuri.code@gmail.com>

The reserved page builders fill in the PS Poll template with the
SET_80211_PS_POLL_* macros from base.h, which write at fixed byte
offsets into a u8 buffer. The AID macro stores a host order u16, so
the frame is only correct on a little endian machine.

Point at the template with struct ieee80211_pspoll from
<linux/ieee80211.h> instead. Its aid member is __le16, so the AID goes
through cpu_to_le16() and sparse can check it. The two addresses are
copied with ether_addr_copy() on the struct members. Remove the three
macros.

On little endian systems the bytes written are the same as before.
