Fix RGMII-ID handling in gianfar

2007-07-18T22:29:37+00:00

The TSEC/eTSEC can detect the interface to the PHY automatically,
but it isn't able to detect whether the RGMII connection needs internal
delay.  So we need to detect that change in the device tree, propagate
it to the platform data, and then check it if we're in RGMII.  This fixes
a bug on the 8641D HPCN board where the Vitesse PHY doesn't use the delay
for RGMII.

gianfar: add support for SGMII

2007-07-09T02:16:38+00:00

Add code for initialising and configuring TBI interface and
programming it for connecting to on-chip SERDES (Lynx PHY)
in case of SGMII mode selected through HRCW at reset.

also add defines for TBI register configuration. TBI
interface is programmed towards the SERDES.

refactored mdio read/write functions to differentiate
programming local interface MII regs (e.g., for TBI) from
always programming the mdio master (TSEC1, for programming
the PHYs).

gianfar: Fix typo bug introduced by move to udp_hdr()

2007-06-29T05:12:04+00:00

In commit 4bedb45203eab92a87b4c863fe2d0cded633427f both the udp and tcp
cases where changed to use udp_hdr() instead of leaving the tcp case
alone and fixing with tcp_hdr().

This ended up causing random behavior with TCP connections because
of looking for tcp_hdr()->check in the wrong place.

network drivers: eliminate unneeded kill_vid code

2007-06-03T15:44:20+00:00

Many drivers had code that did kill_vid, but they weren't doing vlan
filtering. With new API the stub is unneeded unless device sets
NETIF_F_HW_VLAN_FILTER.

Bad habit: I couldn't resist fixing a couple of nearby style things
in acenic, and forcedeth.

gianfar: Add I/O barriers when touching buffer descriptor ownership.

2007-05-18T00:43:15+00:00

The hardware must not see that is given ownership of a buffer until it is
completely written, and when the driver receives ownership of a buffer,
it must ensure that any other reads to the buffer reflect its final
state.  Thus, I/O barriers are added where required.

Without this patch, I have observed GCC reordering the setting of
bdp->length and bdp->status in gfar_new_skb.  Hardware reordering
was also theoretically possible.

[SK_BUFF]: Introduce skb_network_header_len

2007-04-26T05:26:19+00:00

For the common sequence "skb->h.raw - skb->nh.raw", similar to skb->mac_len,
that is precalculated tho, don't think we need to bloat skb with one more
member, so just use this new helper, reducing the number of non-skbuff.h
references to the layer headers even more.
