2019-12-01r8169: fix resume on cable plug-inHeiner Kallweit1-0/+1
It was reported [0] that network doesn't wake up on cable plug-in with certain chip versions. Reason is that on these chip versions the PHY doesn't detect cable plug-in when being in power-down mode. So prevent the PHY from powering down if WoL is enabled.

As this does not represent a correctness issue, do not log the resulting MCDI errors. Add a debug-level message under the (by default disabled) rx_status category instead; and take the opportunity to do a little extra expiry work. Since there are now multiple workitems able to call __efx_filter_rfs_expire on a given channel, it is possible for them to race and thus pass quotas which, combined, exceed rfs_filter_count.

Hence, the DMA address in the first entry of the SGL can start after the packet headers. Currently, unmap_sgl() tries to unmap from this wrong offset, instead of the originally mapped DMA address. So, use existing unmap_skb() instead, which takes originally saved DMA addresses as input.

2019-11-22ice: add helpers for virtchnlJesse Brandeburg1-71/+63
The virtchannel interface was repeating a lot of strings and wasting storage space in the kernel. There was also inconsistent messages for the same thing. Consolidate all those messages and bit checks into a couple of helper functions. Also, reduce stack space usage by simplifying getting the pointer to the pf using a helper.
