      cnic: Refactor code and mark expected switch fall-through · 950347f5
      由 Gustavo A. R. Silva 提交于 
      In preparation to enabling -Wimplicit-fallthrough, refactor code a
bit and mark switch cases where we are expecting to fall through.

This patch fixes the following warning:

drivers/net/ethernet/broadcom/cnic.c: In function ‘cnic_cm_process_kcqe’:
drivers/net/ethernet/broadcom/cnic.c:4044:11: warning: this statement may fall through [-Wimplicit-fallthrough=]
    opcode = L4_KCQE_OPCODE_VALUE_CLOSE_COMP;
drivers/net/ethernet/broadcom/cnic.c:4050:2: note: here
  case L4_KCQE_OPCODE_VALUE_RESET_RECEIVED:
  ^~~~

Warning level 3 was used: -Wimplicit-fallthrough=3

Notice that, in this particular case, the code comment is modified
in accordance with what GCC is expecting to find.

This patch is part of the ongoing efforts to enable
-Wimplicit-fallthrough.

      由 Stanislav Fomichev 提交于 
      Update all users of eth_get_headlen to pass network device, fetch
network namespace from it and pass it down to the flow dissector.
This commit is a noop until administrator inserts BPF flow dissector

      net: move skb->xmit_more hint to softnet data · 6b16f9ee
      由 Florian Westphal 提交于 
      There are two reasons for this.

First, the xmit_more flag conceptually doesn't fit into the skb, as
xmit_more is not a property related to the skb.
Its only a hint to the driver that the stack is about to transmit another
packet immediately.

Second, it was only done this way to not have to pass another argument
to ndo_start_xmit().

We can place xmit_more in the softnet data, next to the device recursion.
The recursion counter is already written to on each transmit. The "more"
indicator is placed right next to it.

Drivers can use the netdev_xmit_more() helper instead of skb->xmit_more
to check the "more packets coming" hint.

skb->xmit_more is retained (but always 0) to not cause build breakage.

This change takes care of the simple s/skb->xmit_more/netdev_xmit_more()/
conversions.  Remaining drivers are converted in the next patches.

      net: remove 'fallback' argument from dev->ndo_select_queue() · a350ecce
      由 Paolo Abeni 提交于 
      After the previous patch, all the callers of ndo_select_queue()
provide as a 'fallback' argument netdev_pick_tx.
The only exceptions are nested calls to ndo_select_queue(),
which pass down the 'fallback' available in the current scope
- still netdev_pick_tx.

We can drop such argument and replace fallback() invocation with
netdev_pick_tx(). This avoids an indirect call per xmit packet
in some scenarios (TCP syn, UDP unconnected, XDP generic, pktgen)
with device drivers implementing such ndo. It also clean the code
a bit.

Tested with ixgbe and CONFIG_FCOE=m

With pktgen using queue xmit:

      bnxt_en: Drop oversize TX packets to prevent errors. · 2b3c6885
      由 Michael Chan 提交于 
      There have been reports of oversize UDP packets being sent to the
driver to be transmitted, causing error conditions.  The issue is
likely caused by the dst of the SKB switching between 'lo' with
64K MTU and the hardware device with a smaller MTU.  Patches are
being proposed by Mahesh Bandewar <maheshb@google.com> to fix the
issue.

In the meantime, add a quick length check in the driver to prevent
the error.  The driver uses the TX packet size as index to look up an
array to setup the TX BD.  The array is large enough to support all MTU
sizes supported by the driver.  The oversize TX packet causes the
driver to index beyond the array and put garbage values into the
TX BD.  Add a simple check to prevent this.
