RE: [PATCH v3 07/11] hv_netvsc: Use HV_HYP_PAGE_SIZE for Hyper-V communication

From: Boqun Feng <redacted> Sent: Thursday, September 10, 2020 7:35 AM

When communicating with Hyper-V, HV_HYP_PAGE_SIZE should be used since
that's the page size used by Hyper-V and Hyper-V expects all
page-related data using the unit of HY_HYP_PAGE_SIZE, for example, the
"pfn" in hv_page_buffer is actually the HV_HYP_PAGE (i.e. the Hyper-V
page) number.

In order to support guest whose page size is not 4k, we need to make
hv_netvsc always use HV_HYP_PAGE_SIZE for Hyper-V communication.
