macb: Fix build with macro'ized readl/writel.

2015-07-27T21:24:48Z

If an architecture defines readl/writel using CPP macros, we get the following kinds of build failure: > > > drivers/net/ethernet/cadence/macb.c:164:1: error: macro "writel" > > > passed 3 arguments, but takes just 2 > macb_or_gem_writel(bp, SA1B, bottom); > ^ Rename the methods so that this doesn't happen.

net/macb: replace macb_count_tx_descriptors() by DIV_ROUND_UP()

2015-07-27T08:10:29Z

macb_count_tx_descriptors() repeats the generic macro DIV_ROUND_UP(). The patch does a replacement. There is no functional change. Signed-off-by: Andy Shevchenko Signed-off-by: David S. Miller

net/macb: suppress compiler warnings

net/macb: use dev_*() when netdev is not yet registered

2015-07-27T08:10:29Z

To avoid messages like macb macb.0 (unnamed net_device) (uninitialized): Cadence caps 0x00000000 macb macb.0 (unnamed net_device) (uninitialized): invalid hw address, using random let's use dev_*() macros. Signed-off-by: Andy Shevchenko Signed-off-by: David S. Miller

net/macb: check if macb_config present

2015-07-27T08:10:29Z

The commit 98b5a0f4a228 introduces jumbo frame support, but also it assumes that macb_config present which is not always true. The configuration without macb_config fails to boot.

net/macb: improve big endian CPU support

2015-07-27T08:10:29Z

The commit a50dad355a53 (net: macb: Add big endian CPU support) converted I/O accessors to readl_relaxed() and writel_relaxed() and consequentially broke MACB driver on AVR32 platforms such as ATNGW100. This patch improves I/O access by checking endiannes first and use the corresponding methods.

Conflicts: drivers/net/ethernet/cadence/macb.c drivers/net/phy/phy.c include/linux/skbuff.h net/ipv4/tcp.c net/switchdev/switchdev.c Switchdev was a case of RTNH_H_{EXTERNAL --> OFFLOAD} renaming overlapping with net-next changes of various sorts. phy.c was a case of two changes, one adding a local variable to a function whilst the second was removing one. tcp.c overlapped a deadlock fix with the addition of new tcp_info statistic values. macb.c involved the addition of two zyncq device entries. skbuff.h involved adding back ipv4_daddr to nf_bridge_info whilst net-next changes put two other existing members of that struct into a union.
