can: make the number of echo skb's configurable · a6e4bc53

由 Wolfgang Grandegger 提交于 10月 08, 2009

This patch allows the CAN controller driver to define the number of echo
skb's used for the local loopback (echo), as suggested by Kurt Van
Dijck, with the function:

  struct net_device *alloc_candev(int sizeof_priv,
                                  unsigned int echo_skb_max);

The CAN drivers have been adapted accordingly. For the ems_usb driver,
as suggested by Sebastian Haas, the number of echo skb's has been
increased to 10, which improves the transmission performance a lot.

bonding: change bond_create_proc_entry() to return void · 38fc0026

由 Nicolas de Pesloüan 提交于 10月 13, 2009

The function bond_create_proc_entry is currently of type int.

Two versions of this function exist:

The one in the ifdef CONFIG_PROC_FS branch always return 0.
The one in the else branch (which is empty) return nothing.

When CONFIG_PROC_FS is undef, this cause the following warning:

drivers/net/bonding/bond_main.c: In function `bond_create_proc_entry':
drivers/net/bonding/bond_main.c:3393: warning: control reaches end of
non-void function

No caller of this function use the returned value.

So change the returned type from int to void and remove the
useless return 0; .

mdio: Advertise pause (flow control) settings even if autoneg is off · 767f4a7c

由 Ben Hutchings 提交于 10月 12, 2009

Currently, if pause autoneg is off we do not set either pause
advertising flag.  If autonegotiation of speed and duplex settings is
enabled, there is no way for the link partner to distinguish this from
our refusing to use pause frames.

We should instead set the advertising flags according to the forced
mode so that the link partner can follow our lead.  This is consistent
with the behaviour of other drivers.

gianfar: Add support for hibernation · be926fc4

由 Anton Vorontsov 提交于 10月 12, 2009

Thanks to various cleanups and refactorings this is now straightforward:
convert the gianfar driver to dev_pm_ops, plus add ->restore() callback
that will fully reinitialize MAC internal registers and BDs.

Note that I kept legacy suspend/resume callbacks so that this patch
doesn't depend on PowerPC changes (i.e. dev_pm_ops support for OF
platform drivers).

gianfar: Factor out gfar_init_bds() from gfar_alloc_skb_resources() · 8728327e

由 Anton Vorontsov 提交于 10月 12, 2009

After hibernation we want to just reinitialize BDs, no need to allocate
anything. So, factor out BDs initialization code from
gfar_alloc_skb_resourses().

Also, teach gfar_init_bds() to reuse already allocated RX SKBs, i.e.
just call gfar_init_rxbdp() if a SKB was already allocated and mapped.

gianfar: Don't needlessly set the wrap bit for the last RX BD · 14231176

由 Anton Vorontsov 提交于 10月 12, 2009

startup_gfar() sets the wrap bit for the last rxbd just after
gfar_new_rxbdp() call, which is issued for all rxbds. And
gfar_new_rxbdp() has the following check already:

	if (bdp == priv->rx_bd_base + priv->rx_ring_size - 1)
		lstatus |= BD_LFLAG(RXBD_WRAP);

So we don't need to set the bit again.

gianfar: Some cleanups for startup_gfar() · ccc05c6e

由 Anton Vorontsov 提交于 10月 12, 2009

We're going to split the startup_gfar() into 3 separate functions,
so let's cleanup the code a little bit so that cosmetic changes
won't distract attention from logical ones.

- Remove needless casts (e.g. (struct sk_buff **)kmalloc());
- Turn 'unsigned long vaddr;' into 'void *vaddr', to avoid casting;
- Add new 'struct device *dev' variable as a shorthand for
  '&priv->ofdev->dev' that is used all over the place, also rename
  'struct net_device *dev' to 'struct net_device *ndev';
- Turn printk(KERN_ERR ...) to pr_err(...), which is shorter;
- Don't return bogus -1 (i.e. -EPERM) when request_irq() fails;
- Turn '&priv->regs->' to just '&regs->'.
