2017-09-28net: hns3: Add support for dynamically buffer reallocationYunsheng Lin3-70/+87
Current buffer allocation can only happen at init, when doing buffer reallocation after init, care must be taken care of memory which priv_buf points to. This patch fixes it by using a dynamic allocated temporary memory. Because we only do buffer reallocation at init or when setting up the DCB parameter, and priv_buf is only used at buffer allocation process, so it is ok to use a dynamic allocated temporary memory.

rss_size is 1, 2, 4, 8, 16, 32, 64, 128, but acutal tc queue size can be any u16 less than 128. If tc queue size is 5, we set the rss_size to 8, indirection table will be used to limit the size of actual queue size. It may cause dropping of receiving packet in hardware if rss_size is not set correctly. For now, each TC has the same rss size.

rx_priv_buf_alloc is used to tell hardware how much buffer is used for rx direction, right now only the private buffer is assigned. For ae_dev that doesn't support DCB, private rx buffer is assigned to zero, only shared rx buffer is used. So not setting the shared rx buffer cause dropping of packet in SSU.
