drivers/net/ethernet: clean up unused assignments

2021-06-03T06:59:16Z

commit 7c8c0291f84027558bd5fca5729cbcf288c510f4 upstream. As part of the W=1 compliation series, these lines all created warnings about unused variables that were assigned a value. Most of them are from register reads, but some are just picking up a return value from a function and never doing anything with it. Fixed warnings: .../ethernet/brocade/bna/bnad.c:3280:6: warning: variable ‘rx_count’ set but not used [-Wunused-but-set-variable] .../ethernet/brocade/bna/bnad.c:3280:6: warning: variable ‘rx_count’ set but not used [-Wunused-but-set-variable] .../ethernet/cortina/gemini.c:512:6: warning: variable ‘val’ set but not used [-Wunused-but-set-variable] .../ethernet/cortina/gemini.c:2110:21: warning: variable ‘config0’ set but not used [-Wunused-but-set-variable] .../ethernet/cavium/liquidio/octeon_device.c:1327:6: warning: variable ‘val32’ set but not used [-Wunused-but-set-variable] .../ethernet/cavium/liquidio/octeon_device.c:1358:6: warning: variable ‘val32’ set but not used [-Wunused-but-set-variable] .../ethernet/dec/tulip/media.c:322:8: warning: variable ‘setup’ set but not used [-Wunused-but-set-variable] .../ethernet/dec/tulip/de4x5.c:4928:13: warning: variable ‘r3’ set but not used [-Wunused-but-set-variable] .../ethernet/micrel/ksz884x.c:1652:7: warning: variable ‘dummy’ set but not used [-Wunused-but-set-variable] .../ethernet/micrel/ksz884x.c:1652:7: warning: variable ‘dummy’ set but not used [-Wunused-but-set-variable] .../ethernet/micrel/ksz884x.c:1652:7: warning: variable ‘dummy’ set but not used [-Wunused-but-set-variable] .../ethernet/micrel/ksz884x.c:1652:7: warning: variable ‘dummy’ set but not used [-Wunused-but-set-variable] .../ethernet/micrel/ksz884x.c:4981:6: warning: variable ‘rx_status’ set but not used [-Wunused-but-set-variable] .../ethernet/micrel/ksz884x.c:6510:6: warning: variable ‘rc’ set but not used [-Wunused-but-set-variable] .../ethernet/micrel/ksz884x.c:6087: warning: cannot understand function prototype: 'struct hw_regs ' .../ethernet/microchip/lan743x_main.c:161:6: warning: variable ‘int_en’ set but not used [-Wunused-but-set-variable] .../ethernet/microchip/lan743x_main.c:1702:6: warning: variable ‘int_sts’ set but not used [-Wunused-but-set-variable] .../ethernet/microchip/lan743x_main.c:3041:6: warning: variable ‘ret’ set but not used [-Wunused-but-set-variable] .../ethernet/natsemi/ns83820.c:603:6: warning: variable ‘tbisr’ set but not used [-Wunused-but-set-variable] .../ethernet/natsemi/ns83820.c:1207:11: warning: variable ‘tanar’ set but not used [-Wunused-but-set-variable] .../ethernet/marvell/mvneta.c:754:6: warning: variable ‘dummy’ set but not used [-Wunused-but-set-variable] .../ethernet/neterion/vxge/vxge-traffic.c:33:6: warning: variable ‘val64’ set but not used [-Wunused-but-set-variable] .../ethernet/neterion/vxge/vxge-traffic.c:160:6: warning: variable ‘val64’ set but not used [-Wunused-but-set-variable] .../ethernet/neterion/vxge/vxge-traffic.c:490:6: warning: variable ‘val32’ set but not used [-Wunused-but-set-variable] .../ethernet/neterion/vxge/vxge-traffic.c:2378:6: warning: variable ‘val64’ set but not used [-Wunused-but-set-variable] .../ethernet/packetengines/yellowfin.c:1063:18: warning: variable ‘yf_size’ set but not used [-Wunused-but-set-variable] .../ethernet/realtek/8139cp.c:1242:6: warning: variable ‘rc’ set but not used [-Wunused-but-set-variable] .../ethernet/mellanox/mlx4/en_tx.c:858:6: warning: variable ‘ring_cons’ set but not used [-Wunused-but-set-variable] .../ethernet/sis/sis900.c:792:6: warning: variable ‘status’ set but not used [-Wunused-but-set-variable] .../ethernet/sfc/falcon/farch.c:878:11: warning: variable ‘rx_ev_pkt_type’ set but not used [-Wunused-but-set-variable] .../ethernet/sfc/falcon/farch.c:877:23: warning: variable ‘rx_ev_mcast_pkt’ set but not used [-Wunused-but-set-variable] .../ethernet/sfc/falcon/farch.c:877:7: warning: variable ‘rx_ev_hdr_type’ set but not used [-Wunused-but-set-variable] .../ethernet/sfc/falcon/farch.c:876:7: warning: variable ‘rx_ev_other_err’ set but not used [-Wunused-but-set-variable] .../ethernet/sfc/falcon/farch.c:1646:21: warning: variable ‘buftbl_min’ set but not used [-Wunused-but-set-variable] .../ethernet/sfc/falcon/farch.c:2535:32: warning: variable ‘spec’ set but not used [-Wunused-but-set-variable] .../ethernet/via/via-velocity.c:880:6: warning: variable ‘curr_status’ set but not used [-Wunused-but-set-variable] .../ethernet/ti/tlan.c:656:6: warning: variable ‘rc’ set but not used [-Wunused-but-set-variable] .../ethernet/ti/davinci_emac.c:1230:6: warning: variable ‘num_tx_pkts’ set but not used [-Wunused-but-set-variable] .../ethernet/synopsys/dwc-xlgmac-common.c:516:8: warning: variable ‘str’ set but not used [-Wunused-but-set-variable] .../ethernet/ti/cpsw_new.c:1662:22: warning: variable ‘priv’ set but not used [-Wunused-but-set-variable] The register reads should be OK, because the current implementation of readl and friends will always execute even without an lvalue. When it makes sense, just remove the lvalue assignment and the local. Other times, just remove the offending code, and occasionally, just mark the variable as maybe unused since it could be used in an ifdef or debug scenario. Only compile tested with W=1.

sis900: remove TxIDLE

2019-06-28T05:38:23Z

Before "sis900: fix TX completion" patch, TX completion was done on TxIDLE interrupt. TX completion also was the only thing done on TxIDLE interrupt. Since "sis900: fix TX completion", TX completion is done on TxDESC interrupt. So it is not necessary any more to set and to check for TxIDLE. Eliminate TxIDLE from sis900. Correct some typos, too.

sis900: fix TX completion

2019-06-22T23:46:32Z

Since commit 605ad7f184b60cfaacbc038aa6c55ee68dee3c89 "tcp: refine TSO autosizing", outbound throughput is dramatically reduced for some connections, as sis900 is doing TX completion within idle states only. Make TX completion happen after every transmitted packet.

ethernet/sis: Replace synchronize_sched() with synchronize_rcu()

2018-11-27T17:21:36Z

Now that synchronize_rcu() waits for preempt-disable regions of code as well as RCU read-side critical sections, synchronize_sched() can be replaced by synchronize_rcu(). This commit therefore makes this change. Signed-off-by: Paul E. McKenney Cc: Francois Romieu Cc: "David S. Miller" Cc:
