qede: Fix single MTU sized packet from firmware GRO flow

In firmware assisted GRO flow there could be a single MTU sized
segment arriving due to firmware aggregation timeout/last segment
in an aggregation flow, which is not expected to be an actual gro
packet. So If a skb has zero frags from the GRO flow then simply
push it in the stack as non gso skb.

qede: Add basic network device support

This patch includes the basic Rx/Tx support for the driver [although
carrier will still never be turned on].
Following this patch the driver registers a network device, initializes
it and prepares it for traffic.

net/qlcnic: fix mac address restore in bond mode 5/6

The bonding driver saves a copy of slaves' original mac address and then
assigns whatever mac as needed to the slave, depending on mode. In at
least modes 5 and 6 (balance-tlb, balance-alb), it often ends up being the
mac address of another slave. On release from the bond, the original mac
address is supposed to get restored via a dev_set_mac_address() call in
the bonding driver's __bond_release_one() function, which calls the
slave's ndo_set_mac_address function, which for qlcnic, is
qlcnic_set_mac().

Now, this function tries to be somewhat intelligent and exit early if
you're trying to set the mac address to the same thing that is already
set. The problem here is that adapter->mac_addr isn't in sync with
netdev->dev_addr. The qlcnic driver still has the original mac stored in
adapter->mac_addr, while the bonding driver has updated netdev->dev_addr,
so qlcnic thinks we're trying to set the same address it already has.

I think the way to go here, since the function updates both netdev and
adapter's stored mac addresses, is to check if either of them doesn't
match the newly requested mac. Simply checking netdev's value only could
result in a similar mismatch and non-update, so look at both.

9 years agobnx2x: fix receive of VF->PF mailbox messages by the PF on big-endian

bnx2x: fix sending VF->PF messages on big-endian

When a VF is sending a message to the PF, it needs to trigger the PF
to tell it the message is ready.
The trigger did not work on ppc64. No interrupt appeared in the PF.

The bug is due to confusion about the layout of struct trigger_vf_zone.
In bnx2x_send_msg2pf() the trigger is written using writeb(), not
writel(), so the attempt to define the struct with a reversed layout on
big-endian is counter-productive.

Most common of those is when taking the dump from a 2-port device.

Sadly, there's no easy way to mask the problematic attentions during the
