There is no module that is dependent on hclge or hclgevf's symbol,
but hns_enet need them to provide ops for it to run. When there is
a need to auto load the hns3 driver, the auto load will fail because
hclge or hclgevf is not loaded.

Hns_enet has already exported the pci table, so this patch exports
the pci table for hclge and hclgevf module too.

VF queue reset flow is different from PF queue reset flow.
VF driver should stop VF queue first, then send message to PF
and PF do the reset. PF should send a response to VF after
PF complete the queue reset, VF can initialize the queue hw
after get the response.
This patch fixes the VF queue reset flow as the correct step.

When changing the mtu, the max frame size also will be changed. The tx
buffer size and the rx buffer size to be allocated are determined by max
frame size. So when max frame size is changed, the tx buffer and rx buffer
need to be reallocated.

When the tc_num is changed, the tx buffer and rx buffer need to be
reallocated too. So calling set_mtu and buffer_alloc separately is better.
