Consider an skb which doesn't match a ptype_base/ptype_specific handler. If
this skb is delivered to a ptype_all handler, it does not count as a drop.
However, if the skb is also processed by an rx_handler which returns

The Network Flow Classification (NFC) support code from IGC driver uses
terms such as 'rule', 'filter', 'entry', 'input' interchangeably when
referring to NFC rules, making it harder to follow the code. This patch

This patch extends MAC address filter internal APIs igc_add_mac_filter()

based on source address.
A new parameters 'type' is added to the APIs to indicate if the filter
type is source or destination. In cas

We are seeing a deadlock in e1000 down when NAPI is being disabled. Looking
over the kernel function trace of the system it appears that the interface

as the NAPI interface is already disabled.

Every time we access the 'etype' and 'vlan_tci' fields from struct
igc_nfc_filter to enable or disable filters in hardware we have to
convert them from big endian to host order so it makes more sense to
simply have these fields in host order.
The byte order conversion should t

This patch adds the prefix 'igc_ethtool_' to all functions defined in

In igc_adapter we keep a sort of shadow copy of RAL and RAH registers.
There is not much benefit in keeping it, at the cost of maintainability,

This patch adds support for Network Flow Classification (NFC) rules

accordingly. It also does some cleanup on igc_get_max_rss_queues().
