[PATCH v2] vdpa/mlx5: Fix firmware error on creation of 1k VQs
A firmware error is triggered when configuring a 9k MTU on the PF after
switching to switchdev mode and then using a vdpa device with larger
(1k) rings:
mlx5_cmd_out_err: CREATE_GENERAL_OBJECT(0xa00) op_mod(0xd) failed, status bad resource(0x5), syndrome (0xf6db90), err(-22)
This is due to the fact that the hw VQ size parameters are computed
based on the umem_1/2/3_buffer_param_a/b capabilities

RODBC : first line of data from query omitted
Dear List,
when reading MS Excel files in R using package RODBC I encountered the
problem of having the first line of data getting omitted.
I read the data as :
> library(RODBC)
> channel1 <- odbcConnectExcel("myFile.xls")
> sheet1 <- sqlQuery(channel1, "SELECT * FROM [Cell measures (1)$]")
# I use sqlQuery() instead of sqlFetch() since the sheet I

Wht's the meaning?
Disk read problem or else?

I added "XIPH_ADD_CFLAGS([-mfpmath=387])" into configure.ac
Still the result is different from SSE version.

tapply() and barplot() help files for 1.8.1
Hi,
I've just upgraded to 1.9.0 and one of my Sweave files that produces a
number of barplots in a standard manner now produces them in a
different way. I have made a couple of small changes to my code to
get the back the output I was getting before upgrading and now (mostly
out of curiosity) would like to understand what has changed.
I *think* I've tracked it down to tapply() and/or
