Eric Dumazet 6ecd09dd35 net: ftgmac100/ftmac100: dont pull too much data
Drivers should pull only ethernet header from page frag
to skb->head.

Pulling 64 bytes is too much for TCP (without options) on IPv4.

However, it makes sense to pull all the frame if it fits the
128 bytes bloc allocated for skb->head, to free one page per
small incoming frame.

Danny Kukawka f2cedb63df net: replace random_ether_addr() with eth_hw_addr_random()
Replace usage of random_ether_addr() with eth_hw_addr_random()
to set addr_assign_type correctly to NET_ADDR_RANDOM.

Change the trivial cases.

v2: adapt to renamed eth_hw_addr_random()

Eric Dumazet 96cd895168 ftmac100: fix skb truesize underestimation
ftmac100 allocates a page per skb fragment. We must account
PAGE_SIZE increments on skb->truesize, not the actual frag length.

If frame is under 64 bytes, page is freed, so increase truesize only for
bigger frames.

Eric Dumazet 5935f81c59 ftgmac100: fix skb truesize underestimation
ftgmac100 allocates a page per skb fragment. We must account
PAGE_SIZE increments on skb->truesize, not the actual frag length.

If frame is under 64 bytes, page is freed, and truesize adjusted.

Jeff Kirsher aaba215ca0 MII: fix Kconfig dependencies for MII
MII Kconfig option is apart of the core networking drivers and
by default NET_CORE is enabled so drivers selecting MII will
have MII enabled as well.  It was found using the randconfig
option during testing, MII would be selected but NET_CORE
could be disabled.  This caused a dependency error.

Resolved the dependency by selecting NET_CORE when MII is
selected.

Jeff Kirsher 88f07484cc drivers/net/ethernet/*: Enabled vendor Kconfig options
Based on finds for Stephen Rothwell, where current defconfig's
enable a ethernet driver and it is not compiled due to the newly
added NET_VENDOR_* component of Kconfig.

This patch enables all the "new" Kconfig options so that current
defconfig's will continue to compile the expected drivers.  In
addition, by enabling all the new Kconfig options does not add
any un-expected options.
