Alex Ng 0ab09befdb hv_netvsc: fix send buffer failure on MTU change ... If MTU is changed the host would reject the send buffer change. This problem is result of recent change to allow changing send buffer size. Every time we change the MTU, we store the previous net_device section count before destroying the buffer, but we don’t store the previous section size. When we reinitialize the buffer, its size is calculated by multiplying the previous count and previous size. Since we continuously increase the MTU, the host returns us a decreasing count value while the section size is reinitialized to 1728 bytes every time. This eventually leads to a condition where the calculated buf_size is so small that the host rejects it.
