Each of these functions has a pair of mutex lock/unlock ops,
both of these ops perform atomic updates of memory (on x86, it boils down to
"lock cmpxchg %reg,mem" insn), which are 4-8 times more expensive than call+return.

When dev_alloc_skb or pci_dma_mapping_error in rtl8180_init_rx_ring fails,
the memory allocated by pci_zalloc_consistent is not freed.
This patch fixes the bug by adding pci_free_consistent
in error handling code.

This enum is already perfectly aliased to enum nl80211_band, and
the only reason for it is that we get IEEE80211_NUM_BANDS out of
it. There's no really good reason to not declare the number of
bands in nl80211 though, so do that and remove the cfg80211 one.

When pci_request_regions in rtl8180_probe fails, pci_disable_device is not
called to disable the device which is enabled by pci_enbale_device.
This patch fixes the problem by adding a new lable in error handling code.

Now that a new mac80211-based driver for Realtek devices has been submitted,
it is time to reorganize the directories. Rather than having directories
rtlwifi and rtl818x be in drivers/net/wireless/, they will now be in
drivers/net/wireless/realtek/. This change simplifies the directory
structure, but does not result in any configuration changes that are
visable to the user.
