      qed*: Management firmware - notifications and defaults · 0fefbfba
      由 Sudarsana Kalluru 提交于 
      Management firmware is interested in various tidbits about
the driver - including the driver state & several configuration
related fields [MTU, primtary MAC, etc.].
This adds the necessray logic to update MFW with such configurations,
some of which are passed directly via qed while for others APIs
are provide so that qede would be able to later configure if needed.

This also introduces a new default configuration for MTU which would
replace the default inherited by being an ethernet device.

      solos-pci: use permission-specific DEVICE_ATTR variants · 89d9123e
      由 Julia Lawall 提交于 
      Use DEVICE_ATTR_RW for read-write attributes.  This simplifies the
source code, improves readbility, and reduces the chance of

      ldmvsw: tx queue stuck in stopped state after LDC reset · 8778b276
      由 Aaron Young 提交于 
      The following patch fixes an issue with the ldmvsw driver where
the network connection of a guest domain becomes non-functional after
the guest domain has panic'd and rebooted.

The root cause was determined to be from the following series of
events:

1. Guest domain panics - resulting in the guest no longer processing
   network packets (from ldmvsw driver)
2. The ldmvsw driver (in the control domain) eventually exerts flow
   control due to no more available tx drings and stops the tx queue
   for the guest domain
3. The LDC of the network connection for the guest is reset when
   the guest domain reboots after the panic.
4. The LDC reset event is received by the ldmvsw driver and the ldmvsw
   responds by clearing the tx queue for the guest.
5. ldmvsw waits indefinitely for a DATA ACK from the guest - which is
   the normal method to re-enable the tx queue. But the ACK never comes
   because the tx queue was cleared due to the LDC reset.

To fix this issue, in addition to clearing the tx queue, re-enable the
tx queue on a LDC reset. This prevents the ldmvsw from getting caught in
this deadlocked state of waiting for a DATA ACK which will never come.
