Revision b9162d20ed493bc0d5ea3016647d636628e1f9d5 authored by Jiangfeng Xiao on 09 July 2019, 03:31:09 UTC, committed by David S. Miller on 09 July 2019, 21:29:26 UTC
The buf unit size of HI13X1_GMAC is cache_line_size,
which is 64, so the address we write to the buf register
needs to be shifted right by 6 bits.

The 31st bit of the PPE_CFG_CPU_ADD_ADDR register
of HI13X1_GMAC indicates whether to release the buffer
of the message, and the low indicates that it is valid.
