Remove unused components from struct dm_priv.
DMFlag is only written to, but never read.
InitDMFlag is assigned to DMFlag and not used elsewhere.
DM_Type is also write-only.
UndecoratedSmoothedPWDB and UndecoratedSmoothedCCK are not used at all.

Type in struct odm_rate_adapt is always DM_Type_ByDriver.
Therefore, bUseRAMask is always true.
Remove the constant components, unused defines and dead code.

Use the is_broadcast_ether_addr function to check for a
broadcast address.

The eth_broadcast_addr helper assigns the broadcast address to an address
array. Call this function instead of copying the address bytes manually.

Hi Michael,
thanks for spotting this. To be honest, I didn't look at this in much
detail when I wrote the patch.
I suppose the pframe comes from recvbuf2recvframe().
precvframe = rtw_alloc_recvframe(pfree_recv_queue);
with
struct __queue *pfree_recv_queue = &precvpriv->free_recv_queue;
This should be initialised in _rtw_init_recv_priv().
rtw_init_queue(&precvpriv->free_recv_queue);
...
precvpriv->precv_frame_buf = (u8 *)N_BYTE_ALIGMENT((size_t)(precvpriv->pallocated_frame_buf), RXFRAME_ALIGN_SZ);
precvframe = (struct recv_frame *)precvpriv->precv_frame_buf;
and the frames are added to the free_recv_queue.
RXFRAME_ALIGN_SZ is 1<<8.
So pframe should be 256-byte aligned.
GetAddr1Ptr adds 4 to the start of pframe.
I guess we're safe here.

Hmm, some of those arrays in other parts of the kernel have
__aligned(2), others don't...
Can anyone else give some guidance?
Thanks,
Martin

Greg already applied this patch.
I'm not sure why you're looking at precvpriv->precv_frame_buf instead of
"precv_frame->rx_data"? Am I missing something? This is actually a bit
tricky for me to analyze because it gets set in two places:
drivers/staging/r8188eu/core/rtw_recv.c | recvframe_pull | (struct recv_frame)->rx_data | 0-u64max
drivers/staging/r8188eu/hal/usb_ops_linux.c | recvbuf2recvframe | (struct recv_frame)->rx_data | 0-u64max
But the fact that we're using GetAddr1Ptr() on it at all suggests that
it must be aligned and hopefully we've verified that the ->rx_data has
enough data etc... ? This code is much trickier than I like it to be.
Anyway, this patch doesn't introduce bugs that weren't present in the
original.

This array comes after a u32 and it's not packed so it's going to
__aligned(4) already.
