| | | | | | | | | | | | | | | | | | | | | | | | | | Sujith says: This commit breaks the WAN port on my AP96 - DHCP fails. Reverting it fixes the issue. commit b67cc3a0cdd02973610d4d5a63226d1c44841e94 Author: juhosg <juhosg@3c298f89-4303-0410-b956-a3cf2f4a3e73> Date: Fri Feb 8 09:13:18 2013 +0000 generic: ar8216: simplify phy features setup Signed-off-by: Gabor Juhos <juhosg@openwrt.org> git-svn-id: svn://svn.openwrt.org/openwrt/trunk@355183c298f89-4303-0410-b956-a3cf2f4a3e73 This change restores the previous behaviour and moves the code into the ar8216_probe function.

* generic: ar8216: add detach callbackGabor Juhos2013-02-071-5/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current code uses the 'remove' callback to disable packet mangle on the underlying ethernet device. However the attached_dev is always NULL when the 'remove' callback is called by phylib, and this causes NULL pointer dereference, like this: [ 475.300000] CPU 0 Unable to handle kernel paging request at virtual address 000000f0, epc == 801cdcf0, ra == 801c7eac [ 475.310000] Oops[#1]: [ 475.310000] Cpu 0 [ 475.310000] $ 0 : 00000000 00000000 00000000 00000001 [ 475.310000] $ 4 : 828dde00 00000005 828dde08 ffffffff [ 475.310000] $ 8 : 00380081 00380081 82902a40 00000001 [ 475.310000] $12 : 00000037 00370081 00000001 00000000 [ 475.310000] $16 : 82865000 828dde08 828dde00 00000001 [ 475.310000] $20 : 00000080 00460000 00000002 77151448 [ 475.310000] $24 : 00000000 801abfd4 [ 475.310000] $28 : 82cc2000 82cc3d58 0053c3c4 801c7eac [ 475.310000] Hi : 00000007 [ 475.310000] Lo : 00000004 [ 475.310000] epc : 801cdcf0 ar8216_remove+0x1c/0x94 [ 475.310000] Tainted: G O [ 475.310000] ra : 801c7eac phy_remove+0x4c/0x6c [ 475.310000] Status: 1000cc03 KERNEL EXL IE [ 475.310000] Cause : 00800008 [ 475.310000] BadVA : 000000f0 [ 475.310000] PrId : 00019750 (MIPS 74Kc) [ 475.310000] Modules linked in: ath79_wdt ledtrig_usbdev ledtrig_netdev ag71xx(-) nf_nat_irc nf_nat_ftp nf_conntrack_irc nf_conntrack_ft p ipt_MASQUERADE iptable_nat xt_nat nf_nat_ipv4 nf_nat pppoext_conntrack xt_CT iptable_raw xt_state nf_conntrack_ipv4 nf_defrag_ipv4 nf_co nntrack ehci_hcd pppox ipt_REJECT xt_TCPMSS xt_LOG xt_comment xt_multiport xt_mac xt_limit iptable_mangle iptable_filter ip_tables xt_tcpu dp x_tables ppp_async ppp_generic slhc ath9k(O) ath9k_common(O) ath9k_hw(O) ath(O) mac80211(O) usbcore usb_common nls_base crc_ccitt cfg80 211(O) compat(O) arc4 crypto_blkcipher aead ledtrig_timer ledtrig_default_on leds_gpio gpio_button_hotplug(O) [ 475.310000] Process rmmod (pid: 1160, threadinfo=82cc2000, task=83969920, tls=7747c440) [ 475.310000] Stack : 828dde08 802f5004 802f4680 00000001 828ddf70 801c7eac 802f4680 801ad6d8 82902940 00000000 828dde08 802f5004 802f4680 801ad770 00000002 80269d94 00000000 00000001 00000080 828dde08 828dde3c 801ad7fc 82902940 00000000 83859100 00000000 8384dd2c 8384dd2c 828dde08 801ad230 82902800 00000000 00000000 001a0041 828dde08 828dde08 802e80e8 801aac44 00000080 00460000 ...
