From: Alexander Duyck <redacted>

The driver was freeing memory in shutdown instead of remove.  As a result
we were leaking memory if IEEE DCB was enabled and we loaded/unloaded the
driver.  This change moves the freeing of the memory into the remove
routine where it belongs.

Maybe it's a typo, but it cause that igbvf can't be initialized successfully.
Set perm_addr value using valid dev_addr, although which is equal to hw.mac.addr.

From: Yi Zou <redacted>

With the support to bounce buffer added, the skb is coming as nonlinear in the
case of non-DDPed data frames for FCoE, which is mostly ok as the FCoE stack
would take care of that. However, for target mode, we have to set the FC CRC
and FC EOF field to allow the protocol stack to not drop the frame for the last
data frame of that sequence. So fix this by linearizing the skb first before
doing skb_put().
