      e1000e: Cleanup handling of VLAN_HLEN as a part of max frame size · 8084b86d
      由 Alexander Duyck 提交于 
      When the VLAN_HLEN was added to the calculation for the maximum frame size
there seems to have been a number of issues added to the driver.

The first issue is that in some cases the maximum frame size for a device
never really reached the actual maximum frame size as the VLAN header
length was not included the calculation for that value.  As a result some
parts only supported a maximum frame size of either 1496 in the case of
parts that didn't support jumbo frames, and 8996 in the case of the parts
that do.

The second issue is the fact that there were several checks that weren't
updated so as a result setting an MTU of 1500 was treated as enabling jumbo
frames as the calculated value was 1522 instead of 1518.  I have addressed
those by replacing ETH_FRAME_LEN with VLAN_ETH_FRAME_LEN where appropriate.

The final issue was the fact that lowering the MTU below 1500 would cause
the driver to allocate 2K buffers for the rings.  This is an old issue that
was fixed several years ago in igb/ixgbe and I am addressing now by just
replacing == with a <= so that we always just round up to 1522 for anything
that isn't a jumbo frame.

      e1000e: Failure to write SHRA turns on PROMISC mode · b3e5bf1f
      由 David Ertman 提交于 
      Previously, the check to turn on promiscuous mode only took into account
the total number of SHared Receive Address (SHRA) registers and if the
request was for a register within that range.  It is possible that the
Management Engine might have locked a number of SHRA and not allowed a
new address to be written to the requested register.

Add a function to determine the number of unlocked SHRA registers.  Then
determine if the number of registers available is sufficient for our needs,
if not then return -ENOMEM so that UNICAST PROMISC mode is activated.

Since the method by which ME claims SHRA registers is non-deterministic,
also add a return value to the function attempting to write an address
to a SHRA, and return a -E1000_ERR_CONFIG if the write fails.  The error
will be passed up the function chain and allow the driver to also set
UNICAST PROMISC when this happens.

      e1000e: fix .ndo_set_rx_mode for 82579 · 69e1e019
      由 Bruce Allan 提交于 
      Secondary unicast and multicast addresses are added to the Receive
Address registers (RAR) for most parts supported by the driver.  For
82579, there is only one actual RAR and a number of Shared Receive Address
registers (SHRAR) that are shared among the driver and f/w which can be
reserved and write-protected by the f/w.  On this device, use the SHRARs
that are not taken by f/w for the additional addresses.

Add a MAC ops function pointer infrastructure (similar to other MAC
operations in the driver) for setting RARs, introduce a new rar_set
function for 82579 and convert the existing code that sets RARs on other
devices to a generic rar_set function.
