I have a solution for this issue,
please find out if its the right way

htt.h:2226

/*
 * Should be: sizeof(struct htt_host_rx_desc) + max rx MSDU size,
>> * sizeof(struct htt_host_rx_desc) 360 bytes + max MPDU/~MDSU size
802.11AC 16.384 bytes (2^14) + (2^9)
 * rounded up to a cache line size.
 */
>> #define HTT_RX_BUF_SIZE 16896
#define HTT_RX_MSDU_SIZE (HTT_RX_BUF_SIZE - (int)sizeof(struct
htt_rx_desc))





htt_rx.c:1390, ath10k_htt_rx_h_undecap_raw

if (WARN_ON_ONCE(!(is_first && is_last) && !msdu_limit_err))
        return;

/* We see zero length msdus and greater max lenght msdus,
 * not sure why. At least don't try to trim it further.
 */
>> if (unlikely(msdu->len < FCS_LEN || msdu->len > HTT_RX_MSDU_SIZE))

skb_trim(msdu, msdu->len - FCS_LEN);
